BACKGROUND

Cardiovascular disease is one of the leading causes of death in the United States and most European countries. It is estimated that over 70 million people in the United States alone suffer from a cardiovascular disease or disorder including but not limited to high blood pressure, coronary heart disease, dyslipidemia, congestive heart failure and stroke.

Lovaza®, a lipid regulating agent, is indicated as an adjunct to diet to reduce triglyceride levels in adult patients with very high triglyceride levels. Unfortunately, Lovaza® can significantly increase LDL-C and/or non-HDL-C levels in some patients. A need exists for improved treatments for cardiovascular diseases and disorders.

SUMMARY

In various embodiments, the present disclosure provides methods of treating and preventing cardiovascular diseases and disorders.

DETAILED DESCRIPTION

While the present disclosure is capable of being embodied in various forms, the description below of several embodiments is made with the understanding that the present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated. Headings are provided for convenience only and are not to be construed to limit the invention in any manner. Embodiments illustrated under any heading may be combined with embodiments illustrated under any other heading.

The use of numerical values in the various quantitative values specified in this application, unless expressly indicated otherwise, are stated as approximations as though the minimum and maximum values within the stated ranges were both preceded by the word “about.” It is to be understood, although not always explicitly stated, that all numerical designations are preceded by the term “about.” It is to be understood that such range format is used for convenience and brevity and should be understood flexibly to include numerical values explicitly specified as limits of a range, but also to include all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified. For example, a ratio in the range of about 1 to about 200 should be understood to include the explicitly recited limits of about 1 and about 200, but also to include individual ratios such as about 2, about 3, and about 4, and sub-ranges such as about 10 to about 50, about 20 to about 100, and so forth. It also is to be understood, although not always explicitly stated, that the reagents described herein are merely exemplary and that equivalents of such are known in the art.

The term “about,” as used herein when referring to a measurable value such as an amount or concentration and the like, is meant to encompass variations of 20%, 10%, 5%, 1%, 0.5%, or even 0.1% of the specified amount.

The term “derivative,” as used herein when referring to a fatty acid, is meant to encompass any modified form of the fatty acid that was derived for example, by a chemical reaction from the fatty acid in free acid form (i.e., terminal carboxylic acid functional group). Non-limiting examples of fatty acid derivatives as used herein include alkyl esters such as methyl esters, propyl esters, butyl esters, or ethyl esters, a salt of the fatty acid such as a lithium, sodium, or potassium salt, or glyceride form of the fatty acid such as a mono-, di-, or triglyceride fatty acid.

In one embodiment, the free fatty acid of eicosapentaenoic acid is administered to the subject and the amount administered is the gram weight sufficient to substantially match the pharmacokinetic profile produced by administration of 4 g of E-EPA per day to a human subject. In another embodiment, a derivative of eicosapentaenoic acid is administered to the subject and the amount administered is the gram weight sufficient to substantially match the pharmacokinetic profile produced by administration of 4 g of E-EPA per day to a human subject. With respect to a dose of 3.7 g per day of eicosapentaenoic acid, a dose-equivalent amount of E-EPA is about 4 g of E-EPA per day.

The phrase “control subject,” as used herein refers to any subject used as a basis for comparison to the test subject. A control subject includes, but is not limited to, any subject who has not been administered the composition, administered a composition other than the test composition (e.g., Lovaza® comprised of 365 mg of E-EPA and 375 mg of E-DHA), or administered a placebo.

The phrase “cardiovascular risk category 1,” as used herein refers to subjects categorized as having an established cardiovascular disease. Patients from cardiovascular risk category 1 were stratified to the secondary prevention cohort. The designations for patients defined by cardiovascular risk category 1 are collectively referred to as: secondary prevention stratum, secondary prevention cohort, and the primary risk category.

The phrase “cardiovascular risk category 2,” as used herein refers to a subject categorized as having diabetes (which itself is a risk factor for cardiovascular disease) and at least one additional risk factor for cardiovascular disease but who does not have an established cardiovascular disease. Patients from cardiovascular risk category 2 were stratified to the primary prevention cohort. The designations for patients defined by cardiovascular risk category 1 are collectively referred to as: primary prevention stratum, primary prevention cohort, and secondary risk category.

Also, the disclosure of ranges is intended as a continuous range including every value between the minimum and maximum values recited as well as any ranges that can be formed by such values. Also disclosed herein are any and all ratios (and ranges of any such ratios) that can be formed by dividing a disclosed numeric value into any other disclosed numeric value. Accordingly, the skilled person will appreciate that many such ratios, ranges, and ranges of ratios can be unambiguously derived from the numerical values presented herein and in all instances such ratios, ranges, and ranges of ratios represent various embodiments of the present disclosure.

The phrase “statistical significance,” as used herein refers to a result from data generated by testing or experimentation is not likely to occur randomly or by chance, but is instead likely to be attributable to a specific cause. Statistical significance is evaluated from a calculated probability (p-value), where the p-value is a function of the means and standard deviations of the data samples and indicates the probability under which a statistical result occurred by chance or by sampling error. A result is considered statistically significant if the p-value is 0.05 or less, corresponding to a confidence level of 95%.

Comprising” or “comprises” is intended to mean that the compositions and methods include the recited elements, but not excluding others. “Consisting essentially of” when used to define compositions and methods, shall mean excluding other elements of any essential significance to the combination for the stated purpose. Thus, a composition consisting essentially of the elements as defined herein would not exclude other materials or steps that do not materially affect the basic and novel characteristic(s) of the claimed invention. “Consisting of” shall mean excluding more than trace elements of other ingredients and substantial method steps. Embodiments defined by each of these transition terms are within the scope of this invention.

In one embodiment, a composition for use in methods of the disclosure comprises eicosapentaenoic acid, or a pharmaceutically acceptable ester, derivative, conjugate or salt thereof, or mixtures of any of the foregoing, collectively referred to herein as “EPA.” The term “pharmaceutically acceptable” in the present context means that the substance in question does not produce unacceptable toxicity to the subject or interaction with other components of the composition. In one embodiment, derivatives of EPA include, but are not limited to, methyl or other alkyl esters, re-esterified monoglycerides, re-esterified diglycerides and re-esterified triglycerides or mixtures thereof. In one embodiment, such derivatives of EPA are administered daily in amounts containing the same number of moles of EPA contained in 4 grams of ethyl icosapentate.

In another embodiment, the EPA comprises an eicosapentaenoic acid ester. In another embodiment, the EPA comprises a C₁-C₅ alkyl ester of eicosapentaenoic acid. In another embodiment, the EPA comprises eicosapentaenoic acid ethyl ester (E-EPA), eicosapentaenoic acid methyl ester, eicosapentaenoic acid propyl ester, or eicosapentaenoic acid butyl ester.

In another embodiment, the EPA is in the form of ethyl-EPA, methyl-EPA, lithium EPA, mono-, di- or triglyceride EPA or any other ester or salt of EPA, or the free acid form of EPA. The EPA may also be in the form of a 2-substituted derivative or other derivative which slows down its rate of oxidation but does not otherwise change its biological action to any substantial degree.

In various embodiments, the present disclosure provides methods of reducing a risk of a cardiovascular event in a subject on statin therapy. In some embodiments, the methods comprise (a) identifying a subject on statin therapy and having a fasting baseline triglyceride level of about 80 mg/dL to about 1500 mg/dL, wherein said subject has established cardiovascular disease or has a high risk of developing cardiovascular disease; and (b) administering to the subject a composition comprising about 1 g to about 4 g of eicosapentaenoic acid (free acid) or derivative thereof (ethyl or methyl ester) per day. In some embodiments, the reduction in a risk of a cardiovascular event is not correlated to a reduction in the subject's triglyceride levels.

In some embodiments, the present disclosure provides methods of reducing a risk of a cardiovascular event in a subject on statin therapy with or without an associated in reduction a baseline triglyceride level of the subject. As such, a reduction of cardiovascular events is not correlated to a reduction in the subject's triglyceride levels. Accordingly, regardless of whether the subject exhibits a reduction in triglyceride levels, the subject experiences a reduction in a risk of a cardiovascular event. In some embodiments, the methods comprise administering to the subject a composition comprising eicosapentaenoic acid or derivative thereof, wherein the subject does not exhibit a statistically significant change in fasting triglyceride levels for a period of time after administration of the composition. In some embodiments, the period of time is about 1 year to about 5 years, about 1 year to about 6 years, about 1 year to about 7 years, about 1 year to about 8 years, or about 1 year to about 9 years. In another embodiment, the subject exhibits a reduction in fasting triglycerides at a period time of greater than about 5 years, greater than about 6 years, greater than about 7 years, greater than about 8 years, greater than about 9 years, or greater than about 10 years.

In some embodiments, the present disclosure provides methods of reducing a risk of total cardiovascular events in a subject on statin therapy. In some embodiments, the methods comprise administering to the subject a composition comprising eicosapentaenoic acid or derivative thereof. Total cardiovascular events include a first, second, third, fourth, fifth, sixth, eight, ninth, tenth or more cardiovascular event. In some embodiments, the subject has not experienced a cardiovascular event, but is at a high risk for experiencing a cardiovascular event. In some embodiments, the subject has experienced multiple cardiovascular events (i.e., a second, third, fourth, or more) and a reduction in a risk of any subsequent cardiovascular event. In some embodiments, the total cardiovascular events are reduced by at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, or at least about 50%. In some embodiments, the total cardiovascular events are reduced regardless of the subject's fasting baseline triglyceride level. For example, total cardiovascular events are reduced in a subject having a fasting baseline triglyceride level in a low, medium, or high tertile. Subjects in the low baseline fasting triglyceride tertile have triglyceride levels between about 80 mg/dL to about 190 mg/dL (median triglyceride level of 160 mg/dL), subjects in the medium baseline fasting triglyceride tertile have triglyceride levels between about 191 mg/dL to about 250 mg/dL (median triglyceride level of 215 mg/dL), and lastly, subjects in the high baseline fasting triglyceride tertile have triglyceride levels between about 251 mg/dL to about 1400 mg/dL (median triglyceride level of 304 mg/dL).

In some embodiments, the present disclosure provides methods of reducing a cardiovascular event in a subject on statin therapy, the methods comprising instructing or having instructed a caregiver of the subject to inquire if the subject has or previously has had atrial fibrillation and/or flutter, assessing or having assessed whether the subject has or has previously had symptoms of atrial fibrillation and/or flutter, monitoring or having monitored the subject for symptoms of atrial fibrillation and/or flutter, and/or providing or having provided guidance to a caregiver of the subject to monitor the subject for symptoms of atrial fibrillation and/or flutter.

EXAMPLES Example 1: Impact of Icosapent Ethyl on Reducing Cardiovascular Events in High Risk Statin-Treated Patients

Among patients with cardiovascular risk factors who are receiving treatment for secondary or primary prevention, the rates of cardiovascular events remain high. Even in patients receiving appropriate treatment with statins, a substantial residual cardiovascular risk remains. In such patients, an elevated triglyceride level serves as an independent marker for increased ischemic risk, as shown in epidemiological and mendelian randomization studies. In randomized trials, medications that reduce triglycerides, such as extended-release niacin and fibrates, have not reduced the rates of cardiovascular events when administered in addition to appropriate medical therapy, including statins. Further, contemporary trials and recent meta-analyses of omega-3 fatty acid products have not shown benefit in patients receiving statin therapy. Accordingly, the objective of the present study was to determine if and how icosapent ethyl (referenced interchangeably with AMR101 or VASCEPA®) reduced cardiovascular events in patients with elevated triglyceride levels on a statin therapy.

The following study, also referred to as the REDUCE-IT clinical trial, was a large cardiovascular (CV) outcome trial designed to assess CV risk reduction benefit of AMR101 treatment (commercially known as VASCEPA®) versus placebo on the 5-point primary composite endpoint: CV death, non-fatal stroke, non-fatal myocardial infarction (MI), coronary revascularizations, or unstable angina requiring hospitalization.

A multi-center, prospective, randomized, double-blind, placebo-controlled, parallel-group study was performed to evaluate the effect of AMR101 (4 g per day) on cardiovascular health and mortality in hypertriglyceridemic patients with cardiovascular disease or at high risk for cardiovascular disease. The intended expanded indication of the study was treatment with AMR101 as an add-on to statin therapy to reduce the risk of cardiovascular events in patients with clinical cardiovascular disease or with multiple risk factors for cardiovascular disease.

The primary objective of this study was, in patients at LDL-C goal while on statin therapy, with established cardiovascular disease (CVD) or at high risk for CVD, and hypertriglyceridemia (e.g., fasting triglycerides(TG) ≥200 mg/dL and <500 mg/dL), to evaluate the effect of AMR101 4 g daily on time from randomization to first occurrence of any component of the composite of the following major CV events: CV death; nonfatal MI; (including silent MI; electrocardiograms (ECGs) were performed annually for the detection of silent MIs); nonfatal stroke; coronary revascularization; and unstable angina determined to be caused by myocardial ischemia by invasive/non-invasive testing and requiring emergent hospitalization.

The key secondary objective of this study was to evaluate the effect of AMR101 4 g daily on the time from randomization to the first occurrence of the composite of following major CV events: CV death, nonfatal MI (including silent MI), and nonfatal stroke.

Other secondary objectives for this study were to evaluate the effect of therapy on time from randomization to the first occurrence of the following individual or composite endpoints: composite of CV death or nonfatal MI (including silent MI); fatal or nonfatal MI (including silent MI); non-elective coronary revascularization represented as the composite of emergent or urgent classifications; CV death; unstable angina determined to be caused by myocardial ischemia by invasive/non-invasive testing and requiring emergent hospitalization; fatal or nonfatal stroke; composite of total mortality, nonfatal MI (including silent MI), or nonfatal stroke; and total mortality.

Study Population

The population for this study were men and women ≥45 years of age with established CVD, or men and women ≥50 years of age with diabetes in combination with one additional risk factor for CVD. In addition, all patients had atherogenic dyslipidemia defined as on treatment for hypercholesterolemia (but at treatment goal for LDL-C, by treatment with a statin) and hypertriglyceridemia. More details regarding the patient population are listed in the inclusion criteria below. The patients needed to provide consent to participate in the study and were willing and able to comply with the protocol and the study procedures.

Study Periods

This study consisted of the following study periods:

Screening Period:

During the screening period, patients were evaluated for inclusion and exclusion criteria.

At the first visit to the Research Unit (Visit 1), study procedures were performed for evaluation of patient's eligibility in the study. At this screening visit, patients signed an informed consent form before any study procedure was performed; the informed consent form covered the treatment/follow-up period. Based on the evaluation from Visit 1, the following situations occurred:

-   -   Patients who were eligible for participation based on the study         procedures on Visit 1 returned to the Research Unit for Visit 2         (randomization visit) to start the treatment/follow-up period.         This case included, for example, patients at Visit 1 who were on         a stable dose of a statin, were planning to stay on the same         statin and the same dose of the statin, and who did not need to         wash out any non-statin lipid-altering medications.     -   Patients who were not eligible for participation based on the         study procedures on Visit 1 and were unlikely to become eligible         in the next 28 days (for example: unlikely to stabilize statin         dose, unable to wash out non-statin lipid-altering medications,         etc.): these patients were screen failed after Visit 1.     -   Patients that were not eligible for participation in the study         based on the study procedures on Visit 1 could become eligible         in the next 28 days: To become eligible, patients returned at         the discretion of the investigator for a second optional         screening visit (Visit 1.1) at which time the procedures needed         for re-evaluation of the previously failed inclusion/exclusion         criteria were repeated. This case included, for example,         patients who were started on a statin at Visit 1, whose statin         dose was changed at Visit 1, and/or needed to wash out         non-statin lipid-altering medications. The following applied for         these patients:         -   Patients with a change in the statin or statin dose on Visit             1 needed to be on a stable statin dose for at least 28 days             before the lipid qualifying measurements at Visit 1.1. Other             concomitant medications (antidiabetic therapy, for example)             could have been optimized or stabilized during this period.         -   Patients starting a washout at Visit 1 had a washout period             of at least 28 days (only 7 days for bile acid sequestrants)             before the lipid qualifying measurements at Visit 1.1.         -   Patients at Visit 1 who were on a stable dose of a statin,             were planning to stay on the same statin at the same dose,             and who did not need any medication washout, but were asked             to return for Visit 1.1 to repeat one or more of the other             study procedures not related to concomitant medications.     -   Patients who became eligible for participation based on the         additional study procedures at Visit 1.1 returned to the         Research Unit for Visit 2 (randomization visit) to start the         treatment/follow-up period.

At the end of the screening period, patients needed to meet all inclusion and exclusion criteria before they were randomized. Patients who were not eligible for participation after the screening period (based on study procedures at Visit 1 and/or Visit 1.1) could return at a later date for rescreening. These patients needed to re-start with all procedures starting with Visit 1. This included patients who need more time to stabilize one or more conditions or therapies (for example: statin, antidiabetic, antihypertensive, thyroid hormone, HIV-protease inhibitor therapy).

Treatment/Follow-Up Period: Within 42 days after the first screening visit (Visit 1) or within 60 days after the first screening visit (Visit 1) for those patients that had a second screening visit (Visit 1.1), eligible patients entered the treatment/follow-up period. During this period, the patients received study drug during the planned visits at the Research Site and took the study drug while away from the Research Site.

During the visits, study procedures were performed for evaluation of efficacy and safety. A detailed schedule of the procedures is provided below in Table 1.

Study Duration

Patients were randomized at different times during the enrollment period but all ended the study at approximately the same date (i.e., at the study end date) and, therefore, the duration of follow-up differed based on date of randomization. It was planned that all randomized patients received study medication and were followed-up until the study end date. It was expected that a minimum of approximately 1612 primary endpoint events were required during the study. 8179 patients were randomized at multiple Research Sites worldwide over a period of approximately 4.2 years. After randomization, patients were treated and followed up to an estimated maximum of 6.5 years. The study end date was determined to be when approximately 1612 primary efficacy events had been adjudicated. Table 2 shows the study milestones from the first patient screened to the last patient visit and subsequent database lock.

Study Groups

At Visit 2 (Day 0), eligible study patients were randomly assigned to the following treatment groups:

-   -   Group 1: AMR101 (>96% E-EPA) 4 g daily (four 1000 mg capsules         daily)     -   Group 2: placebo (four capsules daily)

The four AMR101 or placebo capsules daily were taken as two capsules in the morning and two capsules in the evening (twice-per-day dosing regimen).

Number of Patients

This was an event-driven trial and it was expected that a minimum of 1612 primary efficacy endpoint events were required during the study. A total of approximately 8179 patients entered into the study to either receive AMR101 or placebo (approximately 4089 patients per treatment group) in order to observe an estimated 1612 events that made up the primary composite endpoint for efficacy.

Randomization

On Day 0, eligible patients were randomized to one of the 2 study groups using a computer-generated randomization schema. Randomized treatment assignment to either AMR101 or placebo in a 1:1 ratio was provided using the internet (lWR).

Blinding

This was a double-blind study. Patients, investigators, pharmacists and other supporting staff at the Research Sites, personnel and designees of the Sponsor, study administrators and personnel at the organization(s) and vendors supporting the study were unaware of the randomization code (i.e., they did not know which study participants were receiving the experimental drug and which were receiving the placebo drug). The study medication AMR101 and placebo capsules were similar in size and appearance to maintain blinding.

During the double-blind treatment/follow-up period, everyone (patients, investigators, pharmacists and other supporting staff at the Research Sites, personnel and designees of the Sponsor, study administrators and personnel at the organization(s) and vendors managing/supporting the study), with the exception of the laboratory personnel performing the analysis, were blinded to individual results of the efficacy laboratory measurements (including lipid values). Individual results from the lipid profile could be unblinded in the event of an emergency for a patient.

Stratification

Participants were assigned to treatment groups stratified by CV risk category, use of ezetimibe and by geographical region (e.g., Westernized, Eastern European, and Asia Pacific countries). There were two CV risk categories:

-   -   CV Risk Category 1: patients with established CVD defined in the         inclusion criteria. Patients with diabetes and established CVD         were included in this category. These patients are defined as         the secondary prevention stratum, primary risk category, and/or         secondary prevention cohort.     -   CV Risk Category 2: patients with diabetes and at least one         additional risk factor for CVD, but no established CVD. These         patients are defined as the primary prevention stratum,         secondary risk category, and/or primary prevention cohort.

Stratification was recorded in the IWR at the time of enrollment. Approximately 70% of randomized patients were in the CV Risk Category 1 and approximately 30% of randomized patients were in the CV Risk Category 2. Enrollment with patients of a CV risk category was stopped when the planned number of patients in that risk category was reached.

Study Population

Inclusion Criteria.

A detailed list of the inclusion criteria for this study is provided in Tables 3-5. Specifically, Table 3 outlines the inclusion criteria for patients in this study whereas Tables 4 and 5 further outline the inclusion criteria based on whether that patient is part of the primary prevention risk category or the secondary prevention risk category of patients, respectively.

TABLE 3 Patient Inclusion Criteria for this Study Study Inclusion Criteria 1 Men or women ≥45 years of age with established CVD (i.e., Primary Prevention Risk Category; see Table 4) or ≥50 years of age with diabetes in combination with one additional risk factor for CVD (i.e., Secondary Prevention Risk Category; see Table 5). 2 Fasting TG levels ≥150 mg/dL (2.26 mmol/L) and <500 mg/dL (5.64 mmol/L). Due to the variability of triglycerides, a 10% allowance existed in the initial protocol, which permitted patients to be enrolled with qualifying triglyceride levels ≥135 mg/dL. Protocol amendment made in May of 2013 changed the lower limit of acceptable triglyceride levels from 150 mg/dL to 200 mg/dL, with no variability allowance. 3 LDL-C >40 mg/dL and ≤100 mg/dL and on stable statin therapy (± ezetimibe) for ≥4 weeks prior to the LDL-C and TG qualifying measurements for randomization. 4 Women who are not pregnant, not breastfeeding, not planning on becoming pregnant, and using an acceptable form of birth control during the study (if of child-bearing potential), unless their sexual partner(s) were surgically sterile or the woman was abstinent. Women of child bearing potential needed a negative urine pregnancy test prior to randomization. 5 Able to provide informed consent and adhere to study schedules. 6 Agree to follow and maintain a physician-recommended diet during the study.

Stable therapy was defined as the same daily dose of the same statin for at least 28 days before the lipid qualification measurements (TG and LDL-C) and, if applicable, the same daily dose of ezetimibe for at least 28 days before the lipid qualification measurements (TG and LDL-C). Patients who had their statin therapy or use of ezetimibe initiated at Visit 1, or had their statin, statin dose and/or ezetimibe dose changed at Visit 1, needed to go through a stabilization period of at least 28 days since initiation/change and had their qualifying lipid measurements measured (TG and LDL-C) after the washout period (at Visit 1.1). Statins may have been administered with or without ezetimibe.

If patients qualified at the first qualification visit (Visit 1) for TG and LDL-C, and met all other inclusion/exclusion criteria, they were randomized at Visit 2. If patients did not qualify at the first qualifying visit (Visit 1), a second re-qualifying visit (Visit 1.1) was allowed. For some patients, because they needed to stabilize medications and/or needed to washout medications, the second re-qualifying visit (Visit 1.1) was needed after the stabilization/washout period.

Women were not considered to be of childbearing potential if they met one of the following criteria as documented by the investigator: they had a hysterectomy, tubal ligation or bilateral oophorectomy prior to signing the informed consent form; and/or they were post-menopausal, defined as ≥1 year since their last menstrual period or have a follicle-stimulating hormone (FSH) level in a menopausal range.

Patients having established CVD (in CV Risk Category 1) were defined as detailed in Table 4.

TABLE 4 Inclusion Criteria for the Primary Prevention Risk Category (i.e., CV Risk Category 1) Primary Prevention Risk Category (i.e., Secondary Prevention Cohort) Defined as men and women ≥45 years of age with one or more of the following: 1 Documented coronary artery disease (CAD; one or more of the following primary criteria must be satisfied):  a.

Excessive alcohol consumption was on average >2 units of alcohol per day. A unit of alcohol was defined as a 12-ounce (350 mL) beer, 5-ounce (150 mL) wine, or 1.5-ounce (45 mL) of 80-proof alcohol for drinks. 20 Mental/psychological impairment or any other reason to expect patient difficulty in complying with the requirements of the study or understanding the goal and potential risks of participating in the study (evaluated at Visit 1).

Study Procedures

The Screening Period for this study included two visits, Visit 1 and Visit 1.1.

Screening Visit (Visit 1):

During Visit 1, patients came to the Research Site for and were instructed to fast for at least 10 hours before their visit. If patients qualified for randomization based on the procedures at Visit 1, they needed to be randomized within 42 days after Visit 1. The following procedures were performed at the screening Visit 1:

-   -   Obtained signed informed consent;     -   Assigned the patient a patient number;     -   Obtained medical, surgical and family history;     -   Recorded demographics;     -   Obtained height, weight, and body mass index;     -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Obtained a 12-lead electrocardiogram;     -   Evaluated inclusion/exclusion criteria,     -   This included procedures and (fasting) blood samples (for         example, hsCRP, calculated creatinine clearance) as needed to         determine the CV risk category (See inclusion criteria);     -   Obtained fasting blood samples for chemistry and hematology         testing;     -   Obtained a fasting blood sample for the lipid profile (TG, TC,         HDL-C, LDL-C, non-HDL-C, VLDL-C);     -   Performed a urine pregnancy test on women of childbearing         potential;     -   Recorded concomitant medication(s); and     -   Instructed patient to fast for at least 10 hours prior to the         next visit.

Screening Visit (Visit 1.1):

Patients who qualified for study participation after Visit 1 because they meet all inclusion criterion and none of the exclusion criteria, skipped Visit 1.1 and returned to the Research Site for Visit 2 to be randomized and to start the treatment/follow-up period of the study. For these patients, Visit 2 occurred soon after Visit 1. Patients, who did not qualify at Visit 1, returned to the Research Site for a second qualifying visit (Visit 1.1) at the discretion of the investigator. At Visit 1.1, procedures that caused failure of eligibility at Visit 1 were repeated. Patients were eligible for randomization after Visit 1.1 if they meet all inclusion criteria and if they no longer failed the exclusion criteria. If patients were evaluated at Visit 1.1 and qualified for randomization based on the repeated procedures at Visit 1.1, they needed to be randomized within 60 days after Visit 1. For some patients, Visit 1.1 was mandatory at least 28 days after Visit 1 in order to check eligibility. These were patients who at Visit 1 started treatment with a statin, changed their statin, changed the daily dose of their statin, started to washout prohibited medications or started a stabilization period with certain medications (See inclusion/exclusion criteria above for details). Any of these changes at Visit 1 may have affected the qualifying lipid levels and therefore, patients needed to have Visit 1.1 to determine whether they qualified based on lipid level requirements (TG and LDL-C) determined at Visit 1. Other procedures that caused failure of eligibility at Visit 1 were also repeated at Visit 1.1. The following procedures were performed at the screening Visit 1.1:

-   -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Evaluated inclusion/exclusion criteria; only those evaluations         were repeated that deemed the patient not eligible on Visit 1;     -   Obtained fasting blood samples for chemistry and hematology         testing. Only those samples were obtained that deemed the         patient not eligible on Visit 1;     -   Obtained a fasting blood sample for the lipid profile (TG, TC,         HDL-C, LDL-C, non-HDL-C, VLDL-C) if the patient was deemed not         eligible on Visit 1. This included patients who at Visit 1         started treatment with a statin, changed their statin, changed         the daily dose of their statin, started to washout prohibited         medications or started a stabilization period with certain         medications (See inclusion/exclusion criteria for details).         These patients had a fasting blood sample collected at Visit 1.1         for the qualifying lipid values (TG and LDL-C), and the TG and         LDL-C inclusion criteria were evaluated and     -   Recorded concomitant medication(s).

The treatment/follow-up period for this study included Visit 2, Visit 3, and Visits 4-9. Every attempt was made to complete the follow-up visits during the defined window periods.

Randomization Visit (Visit 2; Day 0):

Qualified patients returned to the Research Site for Visit 2. The following procedures were performed at Visit 2:

-   -   Performed physical examination;     -   Obtained weight;     -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Measured waist circumference (one of the factors to diagnose         metabolic syndrome);     -   Obtained a 12-lead electrocardiogram;     -   Evaluated inclusion/exclusion criteria;     -   Obtained fasting blood samples for:         -   Chemistry and hematology testing;         -   Lipid profile (baseline);         -   Biomarker assays (baseline);         -   Genetic testing (optional blood sample); and         -   Archived (in countries and at sites approved by IRB/IEC and             dependent on country regulations).     -   Performed a urine pregnancy test on women of childbearing         potential (must be negative for randomization);     -   Dispensed study drug and record randomization number;     -   Instructed patient on how to take study drug;     -   Administered study drug—Note: Study drug was taken orally with         food following the collection of all fasting blood samples;     -   Assessed for and recorded adverse events;     -   Recorded concomitant medication(s); and     -   Instructed patient:         -   To bring all study supplies with them to the next visit;         -   Not to take study drug on the morning of their next visit;             and         -   To fast for ≥10 hours prior to the next visit.

Visit 3 (Day 120; ˜4 Months):

Patients returned to the Research Site for Visit 3 on Day 120±10 days. The following procedures were performed:

-   -   Physical examination;     -   Obtained weight;     -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Obtained fasting blood samples for:         -   Chemistry and hematology testing; and         -   Lipid profile.     -   Reviewed study drug compliance by unused capsule count; discuss         with and counsel patients about compliance if needed;     -   Administered study drug—Note: Study drug should be taken orally         with food following the collection of all fasting blood samples;     -   Assessed and record efficacy events;     -   Assessed for and record adverse events;     -   Recorded concomitant medication(s);     -   Instructed patient:         -   To bring all study supplies with them to the next visit;         -   Not to take study drug on the morning of their next visit;             and         -   To fast for 10 hours prior to the next visit.

Visits 4, 5, 6, 7, 8, and 9:

At Visit 4: Day 360±10; Visit 5: Day 720±10; Visit 6: Day 1080±10; and Visit 7: Day 1440±10: Visit 8: Day 1800±10, Visit 9: Day 2160±10, the following procedures were performed:

-   -   Physical examination;     -   Obtained weight;     -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Measured waist circumference (collected at Visit 5 only);     -   Obtained a 12-lead electrocardiogram;     -   Obtained fasting blood samples for:         -   Chemistry and hematology testing;         -   Lipid profile;         -   Biomarker assays (collected at Visit 5 only); and         -   Archived (in countries and at sites approved by             international review board (IRB)/independent ethics             committee (IEC) and dependent on country regulations);     -   Reviewed study drug compliance by unused capsule count;         discussed with and counseled patients about compliance if         needed;     -   Administered study drug—Note: Study drug should be taken orally         with food following the collection of all fasting blood samples;     -   Assessed and record efficacy events;     -   Assessed for and record adverse events;     -   Recorded concomitant medication(s); and     -   Instructed patient:         -   To bring all study supplies with them to the next visit;         -   Not to take study drug on the morning of their next visit;             and         -   To fast for ≥10 hours prior to the next visit.

Additional Visits:

The end date of the study was expected for Day 2160 but the actual end date was dependent on the determination of the study end date by the DMC and when approximately 1612 primary efficacy events had occurred. If the actual study end date was later than the expected end date, additional visits were planned between Visit 7 and the Last Visit with a maximum of 360±10 days between visits. If the actual study end date was sooner than the expected end date, fewer visits occurred, and the last visit (See below, section titled Last Visit—End of Study) occurred sooner. On additional visits the same procedures were performed. Irrespective of the number of additional visits, after the DMC had established the end of the study date, there was a last visit with procedures as listed below in section titled Last Visit—End of Study.

Last Visit—End of Study:

All patients completed the study at the same time (within a 30-day window after the study end date), irrespective of the date that they were randomized. The end date of the study was planned for Day 2160 but the actual end date was dependent on the determination of the study end date by the DMC when approximately 1612 primary efficacy events had occurred (event-driven trial). For each patient, the last visit may have occurred within 30 days after the actual study end date as determined by the DMC. However, for the efficacy endpoints based on CV events, only events occurring up to and including the scheduled actual study end date were included in the efficacy analyses. A final follow-up visit was required for all patients. In a rare case that a final follow-up visit did not occur within the 30-day timeframe following the study end date, any attempt to contact the patient was recorded on a special contact form, until/unless appropriate information was obtained. At the Last Visit, the following procedures were performed:

-   -   Physical examination;     -   Obtained weight;     -   Obtained vital signs (systolic and diastolic blood pressure,         heart rate, respiratory rate, and body temperature);     -   Measured waist circumference;     -   Obtained a 12-lead electrocardiogram     -   Obtained fasting blood samples for:         -   Chemistry and hematology testing;         -   Lipid profile;         -   Biomarker assays; and         -   Archived (in countries and at sites approved by IRB/IEC and             dependent on country regulations).     -   Determined study drug compliance by unused capsule count;     -   Assessed and record efficacy events;     -   Assessed for and record adverse events; and     -   Recorded concomitant medication(s).

Telephoned Follow-Up Contact:

Site personnel contacted each patient by telephone on the following study days: Day 60±3 days; Day 180±5 days; Day 270±5 days; Day 450±5 days; Day 540±5 days; Day 630±5 days; Day 810±5 days; Day 900±5 days; Day 990±5 days; Day 1170±5 days; Day 1260±5 days; Day 1350±5 days; Day 1530±5 days; Day 1620±5 days; Day 1710±5 days; Day 1890±5 days; Day 1980±5 days; and Day 2070±5 days.

If the treatment/follow-up period of the study was extended beyond the expected end date (Day 2160), additional follow-up phone calls were made every 3 months in-between additional visits ±5 days. If the treatment/follow period of the study was shorter than the expected end date, less follow-up phone calls were needed. Every attempt was made to talk to each patient within this timeframe. The following information was collected from the patient:

-   -   Possible efficacy endpoints related to CV events. Patients were         asked to return to the Research Site to assess for any endpoints         or events identified;     -   Adverse events;     -   Concomitant medications; and     -   Current address and contact information.

Patients were reminded about the following items:

-   -   To take the study medication according to the dosing schedule         assigned, with food;     -   When to return to the Research Center for the next visit;     -   To bring the unused study medication to the next visit;     -   To not take study drug on the morning of their next visit; and     -   To fast for at least 10 hours prior to the next visit.

Laboratory Procedures

Clinical Laboratory Procedures and Evaluations:

All clinical laboratory determinations for screening and safety were performed by a certified clinical laboratory under the supervision of the Sponsor or its designee. Whenever possible and appropriate, samples for the clinical laboratory procedures were collected after fasting for at least 10 hours. For the purposes of this study, fasting was defined as nothing by mouth except water (and any essential medications). The investigator reviewed and signed all laboratory test reports. At screening, patients who had laboratory values that are outside the exclusionary limits specified in the exclusion criteria were not enrolled in the study (patients would have been considered for the study if values were classified as not clinically significant by the investigator). After randomization, the investigator was notified if laboratory values were outside of their normal range. In this case, the investigator was required to conduct clinically appropriate follow-up procedures.

Safety Laboratory Tests:

The safety parameters were analyzed by a certified clinical laboratory at screening (Visit 1 or Visit 1.1), Randomization visit (Visit 2; Day 0), Visit 3 (Day 120; ˜4 Months) and all other follow-up visits including the Last Visit. The safety laboratory tests included:

-   -   Hematology with complete blood count (CBC), including RBC,         hemoglobin (Hgb), hematocrit (Hct), white cell blood count         (WBC), white cell differential, and platelet count; and     -   Biochemistry panel including total protein, albumin, alkaline         phosphatase, alanine aminotransferase (ALT/SGPT), aspartate         aminotransferase (AST/SGOT), total bilirubin, glucose, calcium,         electrolytes (sodium, potassium, chloride), blood urea nitrogen         (BUN), serum creatinine, uric acid, creatine kinase, and =HbA1c.

Each laboratory result was classified as low (L), normal (N), and high (H) at each visit according to the laboratory-supplied normal range. The shift from baseline was presented for each post-baseline visit and overall post-baseline visits. If multiple measurements for a test parameter were available for a post-baseline patient-visit, the most extreme value was included in the shift table. For shift from baseline to overall post-baseline visits, values from all visits (including unscheduled measurements) were included. The chemistry shift table included fasting lipid parameters. The continuous lipid values were presented as part of the efficacy analysis.

Fasting Lipid Profile:

The fasting lipid panel included: TG, TC, LDL-C, HDL-C, non-HDL-C, and VLDL-C. At all visits, LDL-C was calculated using the Friedewald equation. At Visit 1 and Visit 1.1 direct LDL-C were used if at the same visit TG >400 mg/dL (4.52 mmol/L). These LDL-C values were used for the evaluation of the LDL-C inclusion criterion (LDL-C qualifying measurements for randomization) and for the assessment of changes in the statin therapy when LDL-C was not at goal. At all remaining visits (except Visit 2 and Visit 4) LDL-C was measured by direct LDL cholesterol or by preparative ultracentrifugation if at the same visit TG >400 mg/dL (4.52 mmol/L). In addition, irrespective of the TG levels, at Visit 2 (0 Months of Follow-up, baseline) and at Visit 4 (12 Months of Follow-up), LDL-C were measured by preparative ultracentrifugation. These preparative ultracentrifugation LDL-C measurements were used in the statistical analysis including the calculation of the percent change from baseline (1 year versus baseline). Hopkins LDL-C was calculated for each visit.

Genetic Testing:

A fasting blood sample was stored for future genetic testing at the discretion of the Sponsor. The specifics of this test were determined at a later date. This sample was optional as local regulations may prohibit genetic samples to be collected or shipped outside the country, or patients may not have consented. Research on genetic testing looked for links between genes and certain diseases, including their treatment(s) such as medicines and medical care. The blood samples were collected in the study center with the regular protocol-required labs. Each patient tube with a sample for genetic testing were labeled with patient number only. The site maintained a Subject Code Identification List for cross-reference. The patient number did not contain any identifiable information (i.e., patient initials, date of birth, etc.). Un-analyzed samples were stored frozen by the Sponsor for a period of up to 2 years following the end of the study, at which time they were destroyed. If samples were tested, results were not reported to the patient, parents, relatives, or attending physician and were not recorded in the patient's medical records. There was no follow-up contact with the sites or patients regarding this sample. The subject could withdraw their consent for genetic testing at any time up to analysis, even after the sample had been obtained. The subject could notify the site in writing that they withdraw their consent for the genetic testing portion of the study, and it was documented by the site in the subject chart, as well as captured in the CRF. The lab was notified to pull the sample and destroy it. Potential genetic bioassays may have been performed and may have been as broad as a genome-wide association study (GWAS) or as limited as a single gene-target approach; potential target genes include, but are not limited to the genes encoding: Apo C3, Apo A5, CETP, LPL, PCSK9, TNFα, TNFβ, ALOX5, COX2, FABP genes, haptoglobin 1 and haptoglobin 2.

Biomarkers Assays:

The biomarker assays included: hsCRP, Apo B and hsTnT.

Additional Laboratory Tests:

Additional laboratory tests were performed and included:

-   -   A urine pregnancy test was administered to women of childbearing         potential at certain visits as listed in schedule of procedures         (Table 1). The urine pregnancy tests was performed at the         Research Site utilizing marketed test kits, or at a certified         clinical laboratory;     -   A fasting blood sample (10 mL) for archiving. This sample was         collected only at sites in countries where allowed by local         regulations and at sites for which approved by the IRB or IEC.         The plasma from the archiving sample was stored frozen in 2         separate equal aliquots, and was used at the Sponsor's         discretion to perform repeat analyses described in the protocol         or to perform other tests related to cardiovascular health; and     -   Potential non-genetic bioassays were performed, including but         not limited to: Apo A1, Apo C3, Apo E, NMR lipid profile         (particle size and number), oxidized LDL, Lp(a), Lp-PLA2, serum         fatty-acids concentrations, and gamma-glutamyltransferase (GGT).

Blinding of Laboratory Results:

All efficacy laboratory results during the double-blind period of the trial were blinded (values not provided) to patients, investigators, pharmacists and other supporting staff at the Research Sites, personnel and designees of the Sponsor, study administrators and personnel at the organization(s) and vendors managing and/or supporting the study, with the exception of the laboratory personnel conducting the assays. To ensure patient safety, hsTnT values were reported to the site.

Flagging of Critical Lab Values:

Critical lab values are values that may have warranted medical intervention to avoid possible harm to a patient. Critical lab values were defined in the Laboratory Manual for the study, and the Research Site was notified of the occurrence of a critical lab value (critical high or critical low) by a special annotation (flag) in the laboratory reports provided to the Research Sites. Although laboratory values that were part of the efficacy endpoints during the double-blind period of the study were not provided to the Research Site, the sites were notified when the TG value of a patient sample was >1000 mg/dL (11.29 mmol/L) (critical high TG value) or if the LDL-C values of a patient sample was >130 mg/dL (3.37 mmol/L) (critical high LDL-C value). These critical high values were confirmed by a repeat measurement (new fasting blood sample) within 7 days. TG value of >2000 mg/dL (22.58 mmol/L) were also flagged, so that appropriate medical action could be taken by the investigator as soon as possible.

If TG values were confirmed critically high, patients could be discontinued from study drug with the option to remain on study. The investigator used the best clinical judgment for each patient which included the use of approved TG-lowering medications after patients had discontinued from study drug. If LDL-C values were confirmed critically high, the investigator needed to take appropriate medical action which included: reinforcing/intensifying therapeutic lifestyle changes (including diet and physical activity), increasing the dose of the present statin therapy, adding ezetimibe, or prescribing a more potent statin to lower LDL-C. The investigator used the best clinical judgment for each patient.

Medical Procedures

Medical, Surgical and Family History:

Medical history, including family history and details regarding all illnesses and allergies, date(s) of onset, status of current condition, and smoking and alcohol use were collected on all patients.

Demographics:

Demographic information including day, month, and year of birth, race, and gender were collected for all patients.

Vital Signs and Patient Measurements:

Vital signs included systolic and diastolic blood pressure, heart rate, respiratory rate, and body temperature. Blood pressure was measured using a standardized process:

-   -   Patient sat for ≥5 minutes with feet flat on the floor and         measurement arm supported so that the midpoint of the manometer         cuff was at heart level; and     -   Used a mercury sphygmomanometer or automatic blood pressure         device with an appropriately sized cuff with the bladder         centered over the brachial artery.

Blood pressure was recorded to the nearest 2 mmHg mark on the manometer or to the nearest whole number on an automatic device. A blood pressure reading was repeated 1 to 2 minutes later, and the second reading recorded to the nearest 2 mmHg mark.

The baseline value categories and post-baseline endpoint value categories shown in Table 6 were measured and presented. Definitions for potentially clinically significant (PCS) vital signs treatment-emergent values are defined below in Table 7.

TABLE 6 Vital Signs Value Categories Vital Sign Low Normal High Systolic Blood Pressure ≤90 mmHg >90 mmHg to <160 mmHg ≥160 mmHg Diastolic Blood Pressure ≤50 mmHg >50 mmHg to <100 mmHg ≥100 mmHg Pulse ≤50 beats/min >50 beats/min to <90 beats/min   ≥90 beats/min

TABLE 7 Potentially Clinically Significant Vial Signs Value Definitions Vital Sign PCS Low PCS High Systolic Blood ≤90 mmHg AND ≥160 mmHg AND Pressure decrease of ≥20 mmHg; increase of ≥20 mmHg; ≤90 mmHg; ≥160 mmHg; decrease of ≥20 mmHg increase of ≥20 mmHg Diastolic Blood ≤50 mmHg AND ≥100 mmHg AND increase Pressure decrease of ≥10 mmHg; of >10 mmHg; ≤50 mmHg; ≥100 mmHg; decrease of >10 mmHg increase of 10 mmHg Pulse ≤50 beats/min AND ≥90 beats/min AND decrease of ≥15 beats/min; increase of ≥15 beats/min; ≤50 beats/min; ≥90 beats/min; decrease of ≥15 beats/min increase of ≥15 beats/min

Number (%) of patients with any post-baseline PCS vital sign values was summarized by treatment group. A listing of patients who meet the threshold criteria was provided.

Physical Examination:

A physical examination included source documentation of general appearance, skin, and specific head and neck, heart, lung, abdomen, extremities, and neuromuscular assessments.

Height, Weight and Body Mass Index:

Height and weight were measured. Measurement of weight was performed with the patient dressed in indoor clothing, with shoes removed, and bladder empty.

Waist Circumference:

Waist circumference was measured with a tape measure, as follows: Start at the top of the hip bone then bring the tape measure all the way around—level with the navel. Make sure the tape measure is snug, but without compressing the skin, and that it is parallel with the floor. Patients should not have held their breath while measuring waist circumference.

12-Lead Electrocardiogram (ECG):

ECGs (standard 12-lead) were obtained annually. Site personnel made every attempt to perform a patient's ECG using the same equipment at each visit. ECGs were reviewed by the site for the detection of silent MI. Silent MIs were sent for event adjudication. All post-randomization ECGs (protocol-specified and other) were sent to the CEC for evaluation of silent MI. The 12-lead ECG parameters included Heart Rate (bpm), PR Interval (msec), QRS Interval (msec), QT Interval (msec), and QTc Interval (msec) were measured, and Overall Interpretation and Silent MI (Yes/No) were summarized for all patients at Screening (Visit 1), Randomization visit (Visit 2; Day 0) and all other follow-up visits including the last visit of the study.

A treatment-emergent PCS high value at any time was defined as a change from a value less than or equal to the defined PCS value at baseline to a PCS high value at any post-baseline measurement. A treatment-emergent PCS low value at any time was defined as a change from a value greater than or equal to the lower PCS value at baseline to a PCS low value at any post-baseline measurement. Table 8 provides the PCS ECG values.

TABLE 8 Potentially Clinically Significant ECG Value Definitions ECG Parameter PCS Low PCS High PR Interval <120 msec >120 msec and increase of >20 msec from baseline QRS Interval N/A >110 msec QTc N/A >500 msec

Number (%) of patients with post-baseline PCS ECG values were presented by treatment group. A listing of subjects with potentially clinically significant changes in ECG values was included.

Treatment and Procedures

Treatment Regimen, Dosage, and Duration:

Eligible study patients were randomly assigned on Day 0 to one of the 2 treatment groups. Patients in each group received either 4 g/day AMR101 or placebo for up to 6.5 years, depending on individual date of randomization and overall study stop date according to Table 9. The daily dose of study drug was 4 capsules per day taken as two capsules taken on two occasions per day (2 capsules were given twice daily).

TABLE 9 Dosing Schedule during the Treatment Period Treatment Group Daily Dose Number of Capsules per Day 1 4 g 4 capsules of 1000 mg AMR101 2 Placebo 4 capsules of matching placebo

Patients were instructed to take study drug with food (i.e., with or at the end of their morning and evening meals). On days that patients were scheduled for study visits, the daily dose of study drug was administered by site personnel with food provided by the site following collection of all fasting blood samples. For the purposes of this study, fasting was defined as nothing by mouth except water (and any essential medications) for at least 10 hours. Treatment Assignment

Identification Number:

A unique patient identification number (patient number) was established for each patient at each site. The patient number was used to identify the patient throughout the study and was entered on all documentation. If a patient was not eligible to receive treatment, or if a patient discontinued from the study, the patient number could not be reassigned to another patient. The patient number was used to assign patients to one of the 2 treatment groups according to the randomization schedule.

Drug Randomization:

Only qualified patients who meet all of the inclusion criteria and none of the exclusion criteria were randomized and received study medication starting at Visit 2 (Day 0). Eligible patients were randomly assigned to one of the 2 treatment groups. Randomization was stratified by CV risk category, use of ezetimibe and by geographical region (Westernized, Eastern European, and Asia Pacific countries). Approximately 70% of randomized patients were in the CV Risk Category 1, including patients with established CVD, and approximately 30% of randomized patients were in the CV Risk Category 2, including patients with diabetes and at least one additional risk factor but no established CVD. Enrollment with patients of a CV risk category was stopped when the planned number of patients in that risk category was reached.

Emergency Unblinding:

In an emergency, when knowledge of the patient's treatment assignment was essential for the clinical management or welfare of the patient, the investigator could request the patient's treatment assignment for unblinding. Prior to unblinding the patient's individual treatment assignment, the investigator assessed the relationship of an adverse event to the administration of the study drug (Yes or No). If the blind was broken for any reason, the investigator recorded the date and reason for breaking the blind on the appropriate Case Report Form (CRF) and source documents.

Compliance Control:

Unless clear contraindications arise, patients were strongly encouraged to adhere to their treatment regimen with the study drug for the duration of the trial. Any interruptions of therapy were, if possible, brief (e.g., <4 weeks) and only for clinically indicated reasons, such as adverse events. Discontinuations were discouraged as much as possible. Any discontinuations were based on compelling clinical reasons. For every patient, an assessment of compliance to the study drug treatment regimen was obtained at each scheduled visit. Study medication was dispensed in amounts exceeding the amount required for the study. Patients were instructed to return all unused study medication at the next visit. Compliance to the study drug regimen was evaluated at each visit by counting unused capsules. Discrepancies were evaluated and discussed with each patient to assess compliance. If compliance was unsatisfactory, the patient was counseled about the importance of compliance to the dosing regimen. At the end of the study, the final study medication compliance was determined by unused capsule count.

Study Restrictions

Concomitant Medications During Treatment/Follow-Up Period:

Any medications administered during the study period were documented on the Concomitant Medication CRF. Patients had not taken any investigational agent within 90 days prior to screening. Patients could not participate in any other investigational medication trial while participating in this study. The following non-study drug related, non-statin, lipid-altering medications and supplements, and foods were prohibited during the study (from Visit 1 until after the Last Visit-End of Study), except for compelling medical reasons in ODIS patients:

-   -   niacin >200 mg/day;     -   fibrates;     -   prescription omega-3 fatty acid medications;     -   dietary supplements containing omega-3 fatty acids (e.g.,         flaxseed, fish, krill, or algal oils);     -   bile acid sequestrants;     -   PCSK9 inhibitors;     -   cyclophosphamide; and     -   systemic retinoids.

If any of these products were used during the treatment/follow-up period of the study, it was for compelling medical reasons in ODIS patients, and documented in the Concomitant Medication CRF. If the ODIS patient agreed to restart study medication, the use of excluded medication was discontinued. Foods enriched with omega-3 fatty acids were strongly discouraged after Visit 1 for the duration of the study (does not apply to The Netherlands or Canada only. Therefore, all centers in The Netherlands and Canada ignored this request). The following products were allowed: statins, ezetimibe, and herbal products & dietary supplements not containing omega-3 fatty acids.

Statins:

-   -   The same statin at the same dose was continued until the end of         the study, unless deemed medically necessary to change because         of an adverse event or lack of efficacy (LOE). It was preferred         that if LOE was the determining factor that ezetimibe was added         to the present dose;     -   Switching between a brand name statin and the generic version of         the same statin was allowed at any time during the study;     -   Statins were administered with or without ezetimibe;     -   Based on the FDA recommendation, simvastatin 80 mg was used only         in patients who had been taking this dose for 12 months or more         and had not experienced any muscle toxicity. (See reference: FDA         Drug Safety Communication: Ongoing safety review of high-dose         Zocor (simvastatin) and increased risk of muscle injury.         (http://www.fda.gov/Drugs/DrugSafety/PostmarketDrugSafetynformationforPatie         ntsandProviders/ucm204882.htm); and     -   Changing of the type of statin or the statin dose during the         treatment/follow-up period of the study was only done for         compelling medical reasons and was documented in the CRF.         Maintaining statin therapy throughout the study was important         and, in the rare circumstance that it became medically         compelling to discontinue statin use, the patient could remain         in the study and on study medication with approval from the         Medical Monitor. Under such conditions, resumption of statin         therapy was attempted when/if medically appropriate.     -   If the level of LDL-C exceeded 130 mg/dL (3.37 mmol/L) during         the study (initial measurement and confirmed by a second         determination at least 1 week later), the investigator either         increased the dose of the present statin therapy or added         ezetimibe to lower LDL-C. The investigator used the best         clinical judgment for each patient.

Ldl-C Rescue:

If the level of LDL-C exceeded 130 mg/dL (3.37 mmol/L) during the study (initial measurement and confirmed by a second determination at least 1 week later), the investigator either increased the dose of the present statin therapy or added ezetimibe to lower LDL-C. The investigator used the best clinical judgment for each patient.

No data were available with regard to potential interactions between ethyl-EPA and oral contraceptives. There were no reports suggesting that omega-3 fatty acids, including ethyl-EPA, would decrease the efficacy of oral contraceptives.

Medications that were excluded if not at a stable dose for ≥28 days prior to screening, could be initiated post-randomization if medically warranted (i.e., tamoxifen, estrogens, progestins, thyroid hormone therapy, systemic corticosteroids and HIV-protease inhibitors).

Patient Restrictions:

Beginning at the screening visit, all patients were instructed to refrain from excessive alcohol consumption, to follow a physician recommended diet and to maintain it through the duration of the study. Excessive alcohol consumption is on average 2 units of alcohol per day or drinking 5 units or more for men or 4 units or more for women in any one hour (episodic excessive drinking or binge drinking). A unit of alcohol is defined as a 12-ounce (350 mL) beer, 5-ounce (150 mL) wine, or 1.5-ounce (45 mL) of 80-proof alcohol for drinks.

Investigational Product

Clinical Trial Material:

The following clinical materials were supplied by the Sponsor:

-   -   AMR101 1000 mg capsules     -   Placebo capsules (to match AMR 101 1 g Capsules)

The Sponsor supplied sufficient quantities of AMR101 1000 mg capsules and placebo capsules to allow for completion of the study. The lot numbers of the drugs supplied were recorded in the final study report. Records were maintained indicating the receipt and dispensation of all drug supplies. At the conclusion of the study, any unused study drug was destroyed.

Pharmaceutical Formulations:

AMRI01 1000 mg and placebo capsules (paraffin) were provided in liquid-filled, oblong, gelatin capsules. Each capsule was filled with a clear liquid (colorless to pale yellow in color). The capsules were approximately 25.5 mm in length with a diameter of approximately 9.5 mm.

Labeling and Packaging:

Study medication was packaged in high-density polyethylene bottles. Labeling and packaging was performed according to GMP guidelines and all applicable country-specific requirements. The bottles were numbered for each patient based on the randomization schedule. The patient randomization number assigned by IWR or a designee of the Sponsor for the study (if no IWR system was used), corresponds to the number on the bottles. The bottle number for each patient was recorded in the Electronic Data Capture (EDC) system for the study.

Dispensing Procedures and Storage Conditions

Dispensing Procedures:

At Visit 2 (Day 0), patients were assigned a study drug according to their treatment group determined by the randomization schedule. Once assigned to a treatment group, patients received study drug supplies. At each visit, patients brought unused drug supplies dispensed to them earlier. From the drug supplies assigned to each patient, site personnel administered the drug while the patients were at the Research Site. The investigator or designee contacted the IWR system or a designee of the Sponsor for the study (if no IWR system is used) when any unscheduled replacements of study medication were needed. During the last visit of the treatment period, patients brought the unused drug supplies for site personnel to calculate the final study medication compliance by unused capsule count.

Storage Conditions:

At the Research Sites, study drugs were stored at room temperature, 68° F. to 77° F. (20° C. to 25° C.). Storage temperature did not go below 59° F. (15° C.) or above 86° F. (30° C.) and the drug was stored in the original package. Study drugs were stored in a pharmacy or locked and secure storage facility, accessible only to those individuals authorized by the investigator to dispense the drug. The investigator or designee kept accurate dispensing records. At the conclusion of the study, study site personnel accounted for all used and unused study drug. Any unused study drug was destroyed. The investigator agreed not to distribute study drug to any patient, except those patients participating in the study.

Efficacy Assessments

Specification of Variables and Procedures:

The primary endpoint and the majority of the secondary and tertiary endpoints were based on clinical events related to CVD and mortality. All events occurring between randomization and the study end date (inclusive) were recorded. Only adjudicated events were included in the final analyses.

Primary Efficacy Endpoint:

The primary efficacy endpoint was time from randomization to the first occurrence of the composite of the following clinical events: CV death; nonfatal MI (including silent MI; ECGs were performed annually for the detection of silent MIs); nonfatal stroke; coronary revascularization; and unstable angina determined to be caused by myocardial ischemia by invasive/non-invasive testing and requiring emergent hospitalization. The first occurrence of any of these major adverse vascular events during the follow-up period of the study were included in the incidence.

Secondary Efficacy Endpoints:

The key secondary efficacy endpoint was the time from randomization to the first occurrence of the composite of CV death, nonfatal MI (including silent MI), or nonfatal stroke. Other secondary efficacy endpoints were time from randomization to the first occurrence of the individual or composite endpoints as follows (tested in the order listed):

-   -   The composite of CV death or nonfatal MI (including silent MI);     -   Fatal or nonfatal MI (including silent MI);     -   Non-elective coronary revascularization represented as the         composite of emergent or urgent classifications;     -   CV death;     -   Unstable angina determined to be caused by myocardial ischemia         by invasive/non-invasive testing and requiring emergent         hospitalization;     -   Fatal and nonfatal stroke;     -   The composite of total mortality, nonfatal MI (including silent         MI), or nonfatal stroke; and/or     -   Total mortality.

For the secondary endpoints that count a single event, the time from randomization to the first occurrence of this type of event was counted for each patient. For secondary efficacy endpoints that were composites of two or more types of events, the time from randomization to the first occurrence of any of the event types included in the composite were counted for each patient.

Tertiary Efficacy Endpoints:

The following tertiary endpoints were evaluated as supporting efficacy and safety analyses. Where applicable and unless specified otherwise, endpoint analyses were conducted as time from randomization to the first occurrence of the individual or composite endpoint as follows:

-   -   Total CV events analysis defined as the time from randomization         to occurrence of the first and all recurrent major CV events         defined as CV death, nonfatal MI (including silent MI), nonfatal         stroke, coronary revascularization, or unstable angina         determined to be caused by myocardial ischemia by         invasiveinon-invasive testing and requiring emergent         hospitalization;     -   Primary composite endpoint in subset of patients with diabetes         mellitus at baseline;     -   Primary composite endpoint in the subset of patients with         metabolic syndrome at baseline with waist circumference cut         points specifically set at ≥35 inches (88 cm) for all women and         Asian, Hispanic, or Latino men, and 40 inches (102 cm) for all         other men;     -   Primary composite endpoint in the subset of patients with         impaired glucose metabolism at baseline (Visit 2 FBG of 100-125         mg/dL);     -   Key secondary composite endpoint in the subset of patients with         impaired glucose metabolism at baseline (Visit 2 FBG 100-125         mg/dL);     -   The composite of CV death, nonfatal MI (including silent MI),         nonfatal stroke, cardiac arrhythmia requiring hospitalization of         ≥24 hours, or cardiac arrest;     -   The composite of CV death, nonfatal MI (including silent MI),         non-elective coronary revascularizations (defined as emergent or         urgent classifications), or unstable angina determined caused by         myocardial ischemia by invasive/non-invasive testing and         requiring emergent hospitalization;     -   The composite of CV death, nonfatal MI (including silent MI),         non-elective coronary revascularizations (defined as emergent or         urgent classifications), unstable angina determined caused by         myocardial ischemia by invasive/non-invasive testing and         requiring emergent hospitalization, nonfatal stroke, or PVD         requiring intervention, such as angioplasty, bypass surgery, or         aneurism repair;     -   The composite of CV death, nonfatal MI (including silent MI),         non-elective coronary revascularizations (defined as emergent or         urgent classifications), unstable angina determined caused by         myocardial ischemia by invasive/non-invasive testing and         requiring emergent hospitalization, PVD requiring intervention,         or cardiac arrhythmia requiring hospitalization of 24 hours;     -   New CHF;     -   New CHF as the primary cause of hospitalization;     -   Transient ischemic attack (TIA);     -   Amputation for PVD;     -   Carotid revascularization;     -   All coronary revascularizations defined as the composite of         emergent, urgent, elective, or salvage;     -   Emergent coronary revascularizations;     -   Urgent coronary revascularizations;     -   Elective coronary revascularizations;     -   Salvage coronary revascularizations;     -   Cardiac arrhythmias requiring hospitalization of 24 hours;     -   Cardiac arrest;     -   Ischemic stroke;     -   Hemorrhagic stroke;     -   Fatal or nonfatal stroke in the subset of patients with a         history of stroke prior to baseline;     -   New onset diabetes, defined as Type 2 diabetes newly diagnosed         during the treatment/follow-up period;     -   New onset hypertension, defined as blood pressure ≥140 mmHg         systolic OR ≥90 mm Hg diastolic newly diagnosed during the         treatment/follow-up period;     -   Fasting TG, TC, LDL-C, HDL-C, non-HDL-C, VLDL-C, apo B, hsCRP         (hsCRP and log[hsCRP]), hsTnT, and RLP-C (to be estimated from         standard lipid panel, RLP-C=TC−HDL-C−LDL-C [Varbo 2014]), (based         on ITT estimands):         -   Assessment of the relationship between baseline biomarker             values and treatment effects within the primary and key             secondary composite endpoints;         -   Assessment of the effect of AMR101 on each marker; and         -   Assessment of the relationship between post-baseline             biomarker values and treatment effects within the primary             and key secondary composite endpoints by including             post-baseline biomarker values (for example, at 4 months, or             at 1 year) as a covariate.     -   Change in body weight; and     -   Change in waist circumference.

Where applicable and unless specified otherwise, for the tertiary endpoints that count a single event, the time from randomization to the first occurrence of this type of event was counted in each patient. Similarly, where applicable and unless specified otherwise, for tertiary endpoints that were composites of two or more types of events, the time from randomization to the first occurrence of any of the event types included in the composite was counted in each patient.

Other sensitivity, supportive, and exploratory analyses for the primary efficacy endpoint were carried out, namely, an on-treatment analysis which included primary event onset up to 0 and 30-days after the permanent discontinuation of the drug.

The following clinical events that were positively adjudicated by the Clinical Endpoint Committee were analyzed as tertiary endpoints for the ITT intent-to-treat (ITT) population:

-   -   Composition of total mortality, or congestive heart failure         (CHF);     -   Composite of CV death, or new CHF;     -   Sudden cardiac death;     -   Peripheral artery disease (PAD); and     -   Atrial fibrillation, or atrial flutter.

The above tertiary endpoints were analyzed similarly as the primary endpoint.

In addition, the following were analyzed as tertiary endpoints for the ITT population:

-   -   Relationship between on-treatment high-sensitivity C-reactive         protein (hsCRP) and the primary key secondary endpoints; and     -   Relationship between on-treatment serum eicosapentaenoic acid         (EPA) and the primary and key secondary endpoints.

To assess the relationship between on-treatment hsCRP and the primary and key secondary endpoints, subgroup analyses were carried out as done for the ITT population for patients grouped according to values greater or equal to or less than 2 mg/dL at baseline and at 2 years. To assess the relationship between on-treatment serum EPA and the primary and key secondary endpoints, Kaplan-Meier (KM) curves were produced for AMRI01 treated patients grouped into tertiles based on their values at year 1 and were compared with the placebo-treated patients.

Safety Assessments

Specification of Variables and Procedures:

Safety assessments included adverse events, clinical laboratory measurements (chemistry, hematology), 12-lead ECGs, vital signs (systolic and diastolic blood pressure, heart rate, respiratory rate, and body temperature), weight, waist circumference, and physical examinations as per Study Procedures in Table 1. A complete medical, surgical and family history was completed at Visit 1. All laboratory test results were evaluated by the investigator as to their clinical significance. Any observations at physical examinations or laboratory values considered by the investigator to be clinically significant were considered an adverse event.

Adverse Events:

An adverse event is defined as any untoward medical occurrence, which does not necessarily have a causal relationship with the medication under investigation. An adverse event can therefore be any unfavorable and/or unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of an investigational medication product, whether or not related to the investigational medication product. All adverse events, including observed or volunteered problems, complaints, or symptoms, were recorded on the appropriate CRF. Each adverse event was evaluated for duration, intensity, and causal relationship with the study medication or other factors.

Adverse events, which included clinical laboratory test variables, were monitored from the time of informed consent until study participation was complete. Patients were instructed to report any adverse event that they experienced to the investigator. Beginning with Visit 2, investigators assessed for adverse events at each visit and recorded the event on the appropriate adverse event CRF.

Wherever possible, a specific disease or syndrome rather than individual associated signs and symptoms was identified by the investigator and recorded on the CRF. However, if an observed or reported sign or symptom was not considered a component of a specific disease or syndrome by the investigator, it was recorded as a separate adverse event on the CRF.

Any medical condition that was present when a patient was screened or present at baseline that did not deteriorate were reported as an adverse event. However, medical conditions or signs or symptoms present at baseline and that changed in severity or seriousness at any time during the study were reported as an adverse event.

Clinically significant abnormal laboratory findings or other abnormal assessments that were detected during the study or were present at baseline and significantly worsened were reported as adverse events or SAEs. The investigator exercised his or her medical and scientific judgment in deciding whether an abnormal laboratory finding, or other abnormal assessment was clinically significant.

The investigator rated the severity (intensity) of each adverse event as mild, moderate, or severe, and also categorized each adverse event as to its potential relationship to study drug using the categories of Yes or No. The severity was defined as:

-   -   Mild—An event that is usually transient in nature and generally         not interfering with normal activities.     -   Moderate—An event that is sufficiently discomforting to         interfere with normal activities.     -   Severe—An event that is incapacitating with inability to work or         do usual activity or inability to work or perform normal daily         activity.

Causality Assessment:

The relationship of an adverse event to the administration of the study drug was assessed according to the following definitions:

-   -   No (unrelated, not related, no relation)—The time course between         the administration of study drug and the occurrence or worsening         of the adverse event rules out a causal relationship and another         cause (concomitant drugs, therapies, complications, etc.) is         suspected.     -   Yes (related, probably related, possibly related)—The time         course between the administration of study drug and the         occurrence or worsening of the adverse event is consistent with         a causal relationship and no other cause (concomitant drugs,         therapies, complications, etc.) can be identified.

The following factors were also considered:

-   -   The temporal sequence from study medication administration;     -   The event occurred after the study medication was given. The         length of time from study medication exposure to event was         evaluated in the clinical context of the event;     -   Underlying, concomitant, intercurrent diseases;     -   Each report was evaluated in the context of the natural history         and course of the disease being treated and any other disease         the patient may have had;     -   Concomitant medication;     -   The other medications the patient was taking or the treatment         the patient received were examined to determine whether any of         them might have caused the event in question;     -   Known response pattern for this class of study medication;     -   Clinical and/or preclinical data may have indicated whether a         particular response was likely to be a class effect;     -   Exposure to physical and/or mental stresses;     -   The exposure to stress might induce adverse changes in the         patient and provide a logical and better explanation for the         event;     -   The pharmacology and pharmacokinetics of the study medication;         and     -   The known pharmacologic properties (absorption, distribution,         metabolism, and excretion) of the study medication were         considered.

Unexpected Adverse Events:

An unexpected adverse event is an adverse event either not previously reported or where the nature, seriousness, severity, or outcome is not consistent with the current Investigator's Brochure.

Serious Adverse Events:

A serious adverse event (SAE) is defined as an adverse event that meets any of the following criteria:

-   -   Results in death;     -   Is life-threatening—The term “life-threatening” in the         definition of “serious” refers to an event in which the patient         was at risk of death at the time of the event. It does not refer         to an event, which hypothetically might have caused death, if it         were more severe;     -   Requires hospitalization or prolongation of existing         hospitalization. In general, hospitalization for treatment of a         pre-existing condition(s) that did not worsen from baseline was         not considered adverse events and was not reported as SAEs;     -   Results in disability/incapacity;     -   Is a congenital anomaly/birth defect; and     -   Is an important medical event. Important medical events that may         not result in death, be life threatening, or require         hospitalization were considered an SAE when, based upon         appropriate medical judgment, they may have jeopardized the         patient and may have required medical or surgical intervention         to prevent one of the outcomes listed above. Examples of such         medical events included allergic bronchospasm requiring         intensive treatment in an emergency room or at home, blood         dyscrasias or convulsions that did not result in inpatient         hospitalizations, or the development of drug dependency.

By design of this study SAEs that were endpoint events were only recorded for the endpoint determination and not captured as SAEs. The intention was that the endpoint events were reported to IRBs as SAEs, unless the IRB required that these were reported. Investigators specifically informed their institution/IRB of this plan and confirm whether or not they wanted the endpoint events reported. By agreement with the US FDA, these endpoints were also not reported to the US FDA as SAEs; rather they were reported as endpoint events. Following adjudication if the event was determined to not meet the criteria for an event, the event was evaluated as an SAE beginning with that day as Day 0.

Adverse Events of Special Interest:

Bleeding-related adverse events, glucose control (fasting blood glucose and HbA1c), and indicators of hepatic disorders (e.g., ALT or AST increases >3×ULN, total bilirubin increases of 2×ULN) were summarized separately and compared between treatment groups.

Serious Adverse Event Reporting—Procedure for Investigators

Initial Reports:

All SAEs occurring from the time of informed consent until 28 days following the last administration of study medication were reported to the Sponsor or designee within 24 hours of the knowledge of the occurrence (this refers to any adverse event that meets any of the aforementioned serious criteria). SAEs that the investigator considered related to study medication occurring after the 28-day follow-up period were also reported to the Sponsor or designee. The investigator was required to submit SAE reports to the Institutional Review Board (IRB) or Independent Ethics Committee (IEC) in accordance with local requirements. All investigators involved in studies using the same investigational medicinal product (IMP) received any Suspected Unexpected Serious Adverse Reaction (SUSAR) reports for onward submission to their local IRB as required. All reports sent to investigators were blinded. In addition, regulatory agencies were notified of SAEs per the requirements of the specific regulatory jurisdiction regulations and laws.

Follow-Up Reports:

The investigator followed the patient until the SAE subsided, or until the condition became chronic in nature, stabilized (in the case of persistent impairment), or the patient died. Within 24 hours of receipt of follow-up information, the investigator updated the SAE form electronically in the EDC system for the study and submitted any supporting documentation (e.g., laboratory test reports, patient discharge summary, or autopsy reports) to the Sponsor or designee via fax or email.

Reporting by the Sponsor:

IRBs and IECs were informed of SUSARs according to local requirements. Cases were unblinded for reporting purposes as required.

Exposure in Utero During Clinical Trials:

If a patient became pregnant during the study, the investigator reported the pregnancy to the Sponsor or designee within 24 hours of being notified. The Sponsor or designee then forwarded the Exposure in Utero form to the investigator for completion. The patient was followed by the investigator until completion of the pregnancy. If the pregnancy ended for any reason before the anticipated date, the investigator notified the Sponsor or designee. At the completion of the pregnancy, the investigator documented the outcome of the pregnancy. If the outcome of the pregnancy met the criteria for immediate classification as an SAE (i.e., postpartum complication, spontaneous abortion, stillbirth, neonatal death, or congenital anomaly), the investigator followed the procedures for reporting an SAE.

Treatment Discontinuation/Patient Withdrawal

Patients could withdraw from the study at any time and for any reason.

Study drug administration could also be discontinued at any time, at the discretion of the investigator. In any case, follow-up for efficacy and safety was continued in subjects that discontinued therapy, but remained in the study (i.e., ODIS patients).

Reasons for Early Study Drug Discontinuation:

Study drug discontinuation was avoided as much as possible, but could have been done for any of the following reasons:

-   -   Patient withdrew consent or requested early discontinuation from         the study for any reason. Patients were encouraged to continue         to participate in the study for the entire duration of the study         even if they choose not to take study medication any longer;     -   Occurrence of a clinical or laboratory adverse event, either         serious or non-serious, at the discretion of the investigator.         The Sponsor or designee was notified if a patient was         discontinued because of an adverse event or laboratory         abnormality. It was recommended that, unless clear         contraindications arise, patients were strongly encouraged to         adhere to their treatment regimen with the study drug for the         duration of the trial. Any interruptions of therapy were, if         possible, brief (e.g., <4 weeks) and only for clinically         indicated reasons, such as adverse events. The following were         considered a reason for discontinuation:         -   ALT >3×ULN and bilirubin >1.5×ULN;         -   ALT >5×ULN;         -   ALT >3×ULN and appearance or worsening of hepatitis;         -   ALT >3×ULN persisting for >4 weeks; and/or         -   ALT >3×ULN and cannot be monitored weekly for 4 weeks     -   Any medical condition or personal circumstance that, in the         opinion of the investigator, exposed the patient to risk by         continuing in the study or precluded adherence to the protocol;     -   Sponsor discontinued the study;     -   Investigative site closure, in the event that:         -   Another investigative site cannot accommodate the patient,             or         -   The patient was unable or unwilling to travel to another             investigative site; and/or     -   A TG value was flagged as critically high, i.e., >1000 mg/dL         (11.29 mmol/L), and confirmed as critically high by a repeat         measurement (new fasting blood sample) within 7 days. In this         case, a patient could be discontinued from study drug (with the         option to remain ODIS) and other lipid-altering medications may         be (re)initiated. If the TG value was flagged as >2000 mg/dL         (22.58 mmol/L) then appropriate medical action was taken by the         investigator as soon as possible.

Occurrence of an outcome event according to the judgment of the investigator was not considered a valid reason for study drug discontinuation. Patients whose treatment with study medication was discontinued early, and had not withdrawn consent, stayed in the study and were monitored until the end of the study. Patients that continued in the study after ≥30 days cessation of therapy were characterized as Off Drug In Study (ODIS). ODIS patients were asked to return to the study site for an interim visit once the patient had been off study drug for >30 days. Procedures at this visit were consistent with those at Visit 5. If not contraindicated, patients also had the option to restart study medication at any point once characterized as ODIS. For patients who discontinued study medication (e.g., for an AE that may or may not have been drug-related), a brief therapy interruption could have been followed with a re-challenge (re-initiating study medication) as soon as clinically appropriate; thereby allowing a causative role for study medication to be confirmed or ruled out and continuing a patient in the study and on study drug if appropriate. The reason for study drug discontinuation or interruption was recorded on the CRF.

Follow-Up after Early Study Drug Discontinuation/Lost to Follow-Up

Patients who prematurely discontinued study drug were not replaced. All randomized patients were followed up until the study end date or death, regardless of whether they discontinued study drug prematurely or not. Any event occurring after early study drug discontinuation was recorded up through the study end date. In order to follow the medical status of the patients, especially when they discontinued the study, investigators were encouraged to obtain information from the patient's primary care practitioner (physician or any other medical care provider). Investigators were also requested to try as much as possible to re-contact those patients at the end of the trial to obtain at least their vital status as well as their status with respect to the primary endpoint, and thus avoided lost to follow-up for the efficacy assessment. If patients were lost to follow-up, the CRF was completed up to the last visit or contact.

Statistics

Randomized Population:

The randomized population included all patients who sign the informed consent form and are assigned a randomization number at Visit 2 (Day 0).

Intent-to-Treat Population:

The ITT population included all patients who were randomized via the IRWS (Interactive Web Response System). All efficacy analyses were performed on the ITT population. Patients were analyzed according to the randomized treatment.

Modified Intent-to-Treat Population:

The Modified Intent-to-Treat (mITT) population included all randomized patients who had the study drug dispensed after randomization. Groups were defined based on the randomized treatment.

Per-Protocol Population:

The per-protocol (PP) population included all mITT patients without any major protocol deviations, and who had ≥80% compliance while on treatment. To be included in the PP population the minimum time on therapy was 90 days.

Safety Population:

All safety analyses were conducted based on the safety population, which is defined as all randomized patients. This was the same as the ITT population.

Statistical Methods:

Safety and efficacy variables were analyzed using appropriate statistical methods that were described in detail in a separate Statistical Analysis Plan (SAP). The SAP was finalized before study unblinding.

Patient Disposition and Demographic/Baseline Characteristics:

The number and percentage of patients was tabulated for each of the following categories for each treatment group:

-   -   Screened (total only);     -   Re-screened and reasons for re-screening (total only);     -   ITT overall and by stratification factors (CV risk, ezetimibe         use, and geographical region);     -   mITT population; overall and by stratification factors (CV risk,         ezetimibe use, and geographical region);     -   PP population; overall and by stratification factors (CV risk,         ezetimibe use, and geographical region);     -   Safety population;     -   Patients who completed the study;     -   Patients who terminated from the trial early and the primary         reason for early termination;     -   Patients who terminated the trial early prior to having a         confirmed primary endpoint event;     -   Patients with complete follow-up, defined as those for whom all         components of the primary endpoint have been ascertained during         the entire observation period (or until death); and     -   Patients who, at the time of study completion, were discontinued         from study drug prematurely, but continued within the study         (i.e. ODIS patients), along with the primary reason.

For randomized patients who discontinued treatment with study drug, the primary reason for discontinuation was listed and summarized by treatment group. Demographic and baseline characteristics, including age, gender, ethnicity, race, height, body weight, BMI, diabetes, hypertension, metabolic syndrome, overweight/obese/normal according to BMI, and diabetes plus obesity were summarized using descriptive statistics by treatment group in the ITT population.

Demographic data and baseline characteristics were compared among treatment groups for the ITT and PP population. Differences in demographic and baseline characteristics were tested using a chi-square test (for categorical variables) or t-test (for continuous variables). The p-values used were considered descriptive, primarily as an assessment of the balance between the two groups. Age in years was calculated using the date of randomization (Visit 2) and the date of birth.

Study Medication Exposure and Compliance:

Study drug exposure was summarized by treatment group using descriptive statistics for each time point and overall. Overall study drug compliance was calculated as the number of doses assumed to be taken relative to scheduled dosing period as follows:

${{Compliance}{\mspace{11mu} \;}(\%)} = {\frac{\left( {{\# \mspace{14mu} {Capsules}\mspace{14mu} {of}\mspace{14mu} {total}{\mspace{11mu} \;}{dispensed}} - {\# \mspace{14mu} {Capsules}\mspace{14mu} {of}\mspace{14mu} {total}\mspace{14mu} {returned}}} \right)}{\left( {{{last}{\mspace{11mu} \;}{dose}\mspace{14mu} {date}} - {{first}\mspace{14mu} {dose}\mspace{14mu} {date}} + 1} \right) \times 4\mspace{14mu} {capsules}\text{/}{day}} \times 100}$

Overall percent compliance was calculated per patient in the ITT and Modified ITT populations and summarized by treatment group using descriptive statistics.

Concomitant Therapies:

Concomitant medication/therapy verbatim terms were coded using the latest available version, prior to data base lock, of the World Health Organization Drug Dictionary and the Anatomical Therapeutic Chemical classification system. The numbers and percentages of patients in each treatment group taking concomitant medications were summarized. All verbatim descriptions and coded terms were listed for all non-study medications.

Analysis of Efficacy:

For efficacy endpoints including CV events, only adjudicated events were included in the final statistical analyses.

Summary Statistics:

Summary statistics (n, mean, standard deviation, median, minimum, and maximum) for the baseline and post-baseline measurements, the percent changes, or changes from baseline were presented by treatment group and by visit for all efficacy variables analyzed. The summary statistics included changes in body weight and body mass index from baseline by treatment group and by visit.

Primary Endpoint Analyses:

The analysis of the primary efficacy endpoint was performed using the log-rank test comparing the 2 treatment groups (AMR101 and placebo) and including the stratification factor “CV risk category”, use of ezetimibe and geographical region (Westernized, Eastern European, and Asia Pacific countries) (each as recorded in the IWR at the time of enrollment) as covariates. The two-sided alpha level for the primary analysis was reduced from 0.05 to account for the interim analyses based on a group sequential design with O'Brien-Fleming boundaries generated using the Lan-DeMets alpha-spending function. The hazard ratio (HR) for treatment group (AMRI 01 vs. placebo) from a Cox proportional hazard model that included the stratification factor was also reported, along with the associated 95% confidence interval (CI). Kaplan-Meier estimates from randomization to the time to the primary efficacy endpoint were plotted.

The size and direction of the treatment effects of the individual components of the composite endpoint and their relative contribution to the composite endpoint were determined as well. All observed data that were positively adjudicated by the CEC, including data after discontinuation of study treatment for patients who discontinued study drug prematurely, were included in the primary analysis. Patients who did not experience a primary efficacy event prior to the end of the study or who withdraw from the study early without a preceding primary efficacy event were censored at the date of their last visit/phone contact. The longest prespecified interval between visits (onsite or phone) was 90 days. In view of the up to 90-day monitoring period for CV events, the primary endpoint for patients who had a non-CV death within 90 days of last contact without having had an earlier CV event was censored at the time of death. The primary endpoint for patients who had a non-CV death more than 90 days after last contact without having had an earlier CV event were censored at the time of last contact.

The primary analysis assumed that all silent MIs occurred on the date of the first tracing indicative of a silent MI; a second (sensitivity) analysis assumed that all silent MIs occurred on the day after the last prior normal ECG; and a third (sensitivity) analysis assumed that all silent MIs occurred at the mid-point between the last normal ECG and the ECG with the new MI. All deaths causally adjudicated as “undetermined” were combined with those adjudicated as “CV deaths” for the primary analysis. A sensitivity analysis of the CV death category was performed that excluded the “undetermined cause of death” cohort.

The primary efficacy analysis was performed on the ITT population. A sensitivity analysis was performed using the mITT and PP populations. As a sensitivity analysis, patients who discontinued study drug prematurely were censored for the primary composite endpoint analysis on the date of drug discontinuation. The primary analysis was repeated using this censoring rule for the mITT population. As a supportive analysis, a multivariable, stratified Cox proportional hazards model was constructed for the primary endpoint to evaluate the treatment effect adjusting for important covariates.

Secondary Endpoint Analyses:

The key secondary hypothesis was tested as part of the confirmatory process only if the primary analysis was statistically significant. For the analysis of secondary efficacy endpoints, the Type 1 error was controlled by testing each endpoint sequentially, starting with the key endpoint. Testing was done at a significance level consistent with that used for the primary endpoint and ceased when a secondary endpoint was found for which treatments did not significantly differ. P-values were presented for all analyses, but they were considered descriptive after the first non-significant result was obtained. Each of the secondary endpoints were analyzed by the same methods described for the primary efficacy endpoint. Kaplan-Meier estimated, the log-rank test stratified by stratification factors used at randomization, and the Cox proportional hazards model including the stratification factors as specified above for the primary efficacy endpoint, were summarized by treatment group. In view of the 90-day monitoring period for CV events, the key secondary endpoint for patients who had a non-CV death within 90 days of last contact without having had an earlier CV event was censored at the time of death. The key secondary endpoint for patients who had a non-CV death more than 90 days after last contact without having had an earlier CV event was censored at the time of last contact. Kaplan-Meier curves stratified by each stratification factor were presented. These analyses were conducted for the ITT population.

Tertiary Endpoints Analyses:

Time-to-event tertiary endpoints were analyzed by the same methods as described for the primary efficacy endpoint. Kaplan-Meier estimates, the log-rank test stratified by stratification factors used at randomization, and the Cox proportional hazards model as specified for the primary efficacy endpoint, were summarized by treatment group. In view of the 90-day monitoring period for CV events, if applicable, tertiary endpoints for patients who had a non-CV death within 90 days of last contact without having had an earlier CV event were censored at the time of death. If applicable, tertiary endpoints for patients who gad a non-CV death more than 90 days after last contact without having had an earlier CV event were censored at the time of last contact. Kaplan-Meier curves stratified by each of the stratification factors were presented.

The fasting lipid panel was tested at Screening (Visit 1 or Visit 1.1), Randomization visit (Visit 2; Day 0), Visit 3 (Day 120; ˜4 Months) and all other follow-up visits including the last visit. For change from baseline to 1 year preparative ultracentrifugation measurements for LDL-C were analyzed, unless this value was missing. If the LDL-C preparative ultracentrifugation values were missing, then another LDL-C value was used, with prioritization of values obtained from LDL-C Direct measurements, followed by LDL-C derived by the Friedewald calculation (only for subjects with TG <400 mg/dL), and finally LDL-C derived using the calculation published by Hopkins University investigators (Martin S S, Blaha M J, Elshazly M B, et al. Comparison of a novel method vs the Friedewald equation for estimating low-density lipoprotein cholesterol levels from the standard lipid profile. JAMA. 2013; 310:2061-8.). In addition, change from baseline to day 120 in LDL-C utilizing Friedewald's and Hopkins methods was analyzed, using the arithmetic mean of LDL-C obtained at Visit 2 (Day 0) and the preceding Visit 1 (or Visit 1.1). If one of these values was missing, the single available LDL-C value was used. LDL-C according to Hopkins was calculated at each visit.

The randomization visit was considered Baseline. If a baseline value was not available from the randomization visit, then the latest screening value was used. For measurements of lipids, lipoproteins and inflammatory markers, the change and the percent change were summarized at each visit. Since these biomarkers are typically not normally distributed, the Wilcoxon rank-sum test was used for treatment comparisons of the percent change from baseline, and medians and quartiles were provided for each treatment group. The medians of the differences between the treatment groups and 95% Cis were estimated with the Hodges-Lehmann method. In addition, shift-tables were generated as appropriate.

As an additional exploratory analysis, the relationship between post-baseline biomarker values and treatment effects with the primary and key secondary endpoints were assessed by adding biomarker values (for example, at 4 months, or at 1 year, etc.) as time-dependent covariates in the Cox proportional hazards model. Diagnostic plots for the proportional hazards assumption were evaluated. Weight was measured at the screening visit and at all follow-up visits, including the last visit of the study. Waist circumference was measured at the randomization visit (Visit 2; Day 0), Visit 5 (Day 720) and the last visit of the study. Descriptive statistics were presented by visit and treatment group for baseline, post-treatment change from baseline, and the percent change from baseline. Analysis methods for repeated measurements were used to compare percent change from baseline between treatments.

In this study, new onset diabetes was defined as Type 2 diabetes newly diagnosed during the treatment/follow-up period (i.e. patients with no history of diabetes at randomization). For purposes of this study, a diagnosis of diabetes was made based on the observation of:

-   -   HbA_(1c)≥6.5%. The test was performed in a laboratory using a         method that is National Glycohemoglobin Standardization Program         (NGSP) certified and standardized to the Diabetes Control and         Complications Trial (DCCT) assay. In the absence of unequivocal         hyperglycemia, HbA_(1c)≥6.5% was confirmed by repeat testing;     -   Fasting plasma glucose (FPG) 2126 mg/dL (7.0 mmol/L). Fasting         was defined as no caloric intake for at least 8 hr. In the         absence of unequivocal hyperglycemia, FPG ≥126 mg/dL (7.0         mmol/L) was confirmed by repeat testing;     -   2-hr plasma glucose ≥200 mg/dL (11.1 mmol/L) during an Oral         Glucose Tolerance Test (OGTT). The test was performed as         described by the World Health Organization, using a glucose load         containing the equivalent of 75 g anhydrous glucose dissolved in         water. In the absence of unequivocal hyperglycemia, 2-hr plasma         glucose ≥200 mg/dL (11.1 mmol/L) during an Oral Glucose         Tolerance Test (OGTT) were confirmed by repeat testing; and/or     -   In a patient with classic symptoms of hyperglycemia or         hyperglycemic crisis, a random plasma glucose 200 mg/dL (11.1         mmol/L).

In the absence of unequivocal hyperglycemia, the first three criteria were confirmed by repeat testing.

Exploratory Subgroup Analyses:

Analyses of the effects that patients off study drug and withdrawn from study have on the primary endpoint were performed. Subgroup analyses of the primary and key secondary endpoints were performed as described for the primary endpoint. For each subgroup, Kaplan-Meier estimates, the log-rank test stratified by stratification factors used at randomization (except where the subgroup was a stratification factor), and HRs and CIs from the Cox proportional hazards model as specified for the primary efficacy endpoint, were summarized by treatment group. Demographic, disease, treatment, and baseline lipid and lipoproteins parameters were explored.

Demographic parameters included: Gender; age at baseline (<65 years and 65 years); race (white and nonwhite, or any other subset with at least 10% of the total number of patients); geographical region (Westernized, Eastern European, and Asia Pacific countries); and baseline ezetimibe use (yes/no).

Disease parameters included: CV risk category; the presence/absence of diabetes at baseline; and renal dysfunction at baseline (estimated glomerular filtration rate [eGFR]<60 mL/min/1.73 m²) using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation as follows:

eGFR=141×min (S _(cr)/κ,1)^(α)×max(S _(cr)/κ,1)^(−1.209)×0.993^(Age)×1.018 [if female]×1.159 [if black]

-   -   Where:         -   S_(cr) is serum creatinine in mg/dL,         -   K is 0.7 for females and 0.9 for males,         -   α is −0.329 for females and −0.411 for males,         -   min indicates the minimum of S_(cr)/κ or 1, and         -   max indicates the maximum of S_(cr)/κ or 1.

Treatment Parameters included: Statin intensity at baseline (statin type and regimen); and statin intensity categories as defined in ACC/AHA Cholesterol Guidelines (Stone 2013) and patient's 10-year CV Risk Score (Goff 2013).

Baseline Lipid and Lipoprotein Parameter included: LDL-C (by tertile); HDL-C (by tertile, and tertile by gender); TG (by tertile, and tertile by gender); RLP-C (by tertile); TG ≥150 mg/dL and TG <150 mg/dL; TG ≥200 mg/dL and TG <200 mg/dL; TG ≥median, TG <median; combined highest tertile for TG and lowest tertile for HDL-C; gender-specific highest tertile for TG and lowest tertile for HDL-C; TG 200 mg/dL with HDL-C 35 mg/dL; hsCRP (53 mg/L and >3 mg/L) and by gender; hsCRP (52 mg/L and >2 mg/L) and by gender; Apo B (by tertile); non-HDL-C (by tertile); baseline hemoglobin A1c (Hb1c) value (<6.5%, ≥6.5%); baseline PAD; and baseline TG levels 150 mg/dL with high-density lipoprotein cholesterol (HDL-C) levels≤40 mg/dL for males and ≤50 mg/dL for females.

A Cox proportional hazard (PH) model as mentioned above but additionally with baseline TG as a covariate were fitted to the data at each interim. Diagnostic plots for the PH assumption were evaluated. The consistency of the treatment effects in subgroups was assessed for the primary and key secondary efficacy endpoints. For each subgroup variable, a Cox PH model with terms for treatment, stratification factors (with the exception of those subgroup variables related to the stratification factors, i.e., CV risk category), subgroup, and treatment-by-subgroup interaction were performed. The main treatment effect was tested with this model. P-values for testing the interaction terms <0.15 were considered significant. Results were presented in a Forest plot.

Subgroup analyses of the primary and key secondary endpoints were performed as described for the primary endpoint. For each subgroup, Kaplan-Meier estimates, the log-rank test stratified by stratification factors used at randomization (except where the subgroup was a stratification factor), and HRs and CIs from the Cox proportional hazards model as specified for the primary efficacy endpoint, were summarized by treatment group. All subgroup analyses were conducted for the ITT, mITT and PP populations.

Interim Efficacy Analysis:

Two interim analyses were planned for the primary efficacy endpoint using adjudicated events when approximately 60% (967 events) and approximately 80% (1290 events) of the total number of primary endpoint events planned (1612) was reached. The planned interim analyses were based on a group-sequential design.

The interim results of the study were monitored by an independent Data Monitoring Committee (DMC). The analyses were performed by the independent statistical team who was unblinded to the treatment assignment and reported only to the DMC. If the study was terminated early following interim analysis, patients were notified promptly and brought in for their final close-out visit, and the final analyses of efficacy and safety included all data through their final visit. All suspected events were adjudicated in a blinded manner by the CEC. The time to event was calculated as the time from randomization to the onset date of the event (as determined by the CEC). Patients who do not experience any of the above events at the time of data cutoff for the interim but were still in the trial were considered censored at the time of their last regular contact before the interim data cutoff.

The alpha-levels for the two protocol prespecified interim analyses and the final analysis are based on a group sequential design (GSD) with O'Brien-Fleming boundaries generated using the Lan-DeMets alpha spending function. The one-sided alpha-levels and boundaries based on a Z-test and the achieved p-values for each of the two interim analyses and the final analysis are given in Table 10.

Analysis of Safety:

All analyses of safety were conducted on the safety population, which was defined as all randomized patients. The safety assessment was based on the frequency of adverse events, physical exams, vital signs and safety laboratory tests. AEs with new onset during the study between the initiation of study drug and 30 days after the last dose of study drug for each patient was considered treatment-emergent (TEAEs). This included any AE with onset prior to initiation of study drug and increased severity after the treatment initiation.

Treatment-emergent adverse events were summarized by system organ class and preferred term, and by treatment. This included overall incidence rates (regardless of severity and relationship to study drug), and incidence rates for moderate or severe adverse events. A summary of SAEs and adverse events leading to early discontinuation (for 30 days) were presented through data listings. Patients who restarted study drug were included in the summary of AEs leading to discontinuation. Safety laboratory tests and vital signs were summarized by post-treatment change from baseline for each of the parameters using descriptive statistics by treatment group. Those patients with significant laboratory abnormalities were identified in data listings. Additional safety parameters were summarized in data listings.

In addition to the treatment-emergent adverse events analyses, analyses on all AEs (serious and non-serious) and all serious AEs were performed.

All AEs included: treatment-emergent adverse event (TEAE) by high level group term (HLGT); TEAE by high level term (HLT); and TEAE by system organ class (SOC), HLGT, HLT, and preferred term (PT) (4-level table).

All SAEs included: treatment emergent SAE by HLGT; treatment emergent SAE by HLT; and treatment emergent SAE by SOC, HLGT, HLT, and PT (4-level table).

Clinical Laboratory Evaluation

The criteria for potentially clinically significant (PCS) laboratory values are provided in Table 11 and Table 12. A treatment-emergent PCS high value at any time was defined as a change from a value less than or equal to the upper reference limit at baseline to a PCS high value at any post-baseline measurement. A treatment-emergent PCS low value at any time was defined as a change from a value greater than or equal to the lower reference limit at baseline to a PCS low value at any post-baseline measurement. Number (%) of patients with any post-baseline PCS laboratory values was summarized by treatment group. A listing of patients with PCS laboratory values at any time, i.e., baseline or at any post-baseline visit, were included.

Drug-Induced Liver Injury (DILI)

DILI cases were investigated through the following analyses:

-   -   A graph of distribution of peak values of alanine         aminotransferase (ALT) versus peak values of total bilirubin         (TBL) during the treatment period was prepared, using a         logarithmic scale. In the graph, for each patient, the peak TBL         times the Upper Limit of Normal (ULN) were plotted against the         peak ALT times the ULN, where the peak TBL and peak ALT may or         may not have happened on the same day of liver testing. The         graph was divided into 4 quadrants with a vertical line         corresponding to 3×ULN for ALT and a horizontal line         corresponding to 2×ULN for TBL. The upper right quadrant was         referred to as the potential Hy's Law quadrant, including         potentially DILI cases.     -   A similar graph was plotted with respect to aspartate         aminotransferase (AST).     -   The individual patient profile of liver function tests (ALT,         AST, alkaline phosphatase [ALP] and TBL) over time was provided         through a graph for all patients with peak value of ALT >3×ULN         and peak value of TBL >2×ULN during the treatment period.     -   Number (%) of patients was provided for the following:         -   ALT or AST >3×ULN;         -   ALT or AST >3×ULN and TBL >2×ULN; and         -   ALT or AST >3×ULN and TBL >2×ULN, and ALP <2×ULN.

Study Design

This was a Phase 3b, multi-center, multi-national, prospective, randomized, double-blind, placebo-controlled, parallel-group study. This was also an event-driven trial comparing the effect of AMR101 vs. placebo in terms of the composite endpoint listed above as the primary endpoint. The placebo contained mineral oil to mimic the color and consistency of icosapent ethyl in AMR101 and was administered in the same capsule fill volume and count as the AMR101. The study accrued a total of 1612 efficacy endpoint events with two planned interim analyses when approximately 967 (60%) and 1290 (80%) of the events had been adjudicated. The study included patients with established CVD (CV Risk Category 1) and patients ≥50 years old with diabetes and at least one additional risk factor for CVD but with CVD not established (CV Risk Category 2). Randomization was stratified by cardiovascular risk stratum which included the secondary-prevention cohort (i.e., CV Risk Category 1) or primary-prevention cohort (i.e., CV Risk Category 2), with the primary prevention cohort capped at 30% of enrolment, use or no use of ezetimibe, and by geographical region. Details of the study design are shown in FIG. 1.

Sample size calculation was based on the assumption of constant hazard, asymmetric recruitment rate overtime and without factoring for dropouts. A risk reduction corresponding to a HR of 0.85 (AMRI01 vs. placebo) was assumed. 1612 events were required to detect this HR with approximately 90% power with one-sided alpha-level at 2.5% and with two interim analyses. The operating characteristics of this design were identical to those of a corresponding group sequential design with a two-sided alpha level of 0.05.

The recruitment period was assumed to be 4.2 years with 20% recruitment in the first year, 40% in the second year, 20% in the third year, 19% in the fourth year and the remaining 1% in the last 0.2 years. The estimated maximum study duration was 6.5 years unless the trial was terminated early for efficacy or safety issues. A one-year event rate of 5.2% (hazard=0.053) in the control arm was also assumed. Under these assumptions the number of patients enrolled was N=7990.

Since this was an events-driven trial, the ‘sample size’ was the number of events rather than the number of patients. The number of events that occurred depends primarily on three factors: how many patients were enrolled; the combined group event rate; and how long the patients were followed. Because of the difficulty in predicting the combined event rate, the Sponsor monitored the event rate as the trial progressed. If the combined event rate was less than anticipated, either increasing the number of patients, extending the length of follow-up, or a balance of adjusting both factors was necessary to achieve the sample size of 1612 events.

At completion of study enrollment, the actual number of patients randomized may have varied from the target number (either original or revised) as a result of the inherent lag between the date the last patient started screening and the date the last patient was randomized.

Completion of Study

The end of the study was at the time the last patient-last visited of the follow-up period of the study. The IRB and IEC were notified about the end of the study according to country-specific regulatory requirements.

Standardized Definitions for the Cardiovascular Trial Endpoint Events

In assessing patients in this clinical trial, the follow definitions were used:

Definition of Cardiovascular Death:

Cardiovascular death includes death resulting from an acute myocardial infarction, sudden cardiac death, death due to congestive heart failure (CHF), death due to stroke, death due to cardiovascular (CV) procedures, death due to CV hemorrhage, and death due to other cardiovascular causes.

Death Due to Acute Myocardial Infarction:

refers to a death by any mechanism (e.g., arrhythmia, CHF) within 30 days after a MI related to the immediate consequences of the MI, such as progressive CHF or recalcitrant arrhythmia. Mortal events that occur after a “break” (e.g., a CHF and arrhythmia-free period of at least a week) should be classified as CV or non-CV death, and if classified as a CV death, should be attributed to the immediate cause, even though the MI may have increased the risk of that event (e.g., the risk of arrhythmic death is increased for many months after an acute MI). Acute MI should be verified to the extent possible by the diagnostic criteria outlined for acute MI (see Definition of MI) or by autopsy findings showing recent MI or recent coronary thrombosis. Death resulting from a procedure to treat a MI (percutaneous coronary intervention (PCI), coronary artery bypass graft surgery (CABG)), or to treat a complication resulting from MI, should also be considered death due to acute MI. Death resulting from an elective coronary procedure to treat myocardial ischemia (i.e., chronic stable angina) or death due to a MI that occurs as a direct consequence of a CV investigation/procedure/operation should be considered as a death due to a CV procedure.

Sudden Cardiac Death:

refers to a death that occurs unexpectedly, not within 30 days of an acute MI, and includes the following deaths: death witnessed and instantaneous without new or worsening symptoms; death witnessed within 60 minutes of the onset of new or worsening cardiac symptoms, unless the symptoms suggest an acute MI; death witnessed and attributed to an identified arrhythmia (e.g., captured on an electrocardiographic (ECG) recording, witnessed on a monitor, or unwitnessed but found on implantable cardioverter-defibrillator review); death after unsuccessful resuscitation from cardiac arrest; death after successful resuscitation from cardiac arrest and without identification of a non-cardiac etiology; and/or unwitnessed death without other cause of death (information regarding the patient's clinical status preceding death should be provided, if available)

General Considerations for Sudden Cardiac Death: A subject seen alive and clinically stable 12-24 hours prior to being found dead without any evidence or information of a specific cause of death should be classified as “sudden cardiac death.” Deaths for which there is no information beyond “patient found dead at home” are classified as “death due to other cardiovascular causes”. (See Definition of Undetermined Cause of Death, for full details below).

Death Due to Congestive Heart Failure:

refers to a death in association with clinically worsening symptoms and/or signs of heart failure (See Definition of Heart Failure Event, for full details below). Deaths due to heart failure can have various etiologies, including single or recurrent myocardial infarctions, ischemic or non-ischemic cardiomyopathy, hypertension, or valvular disease.

Death Due to Stroke:

refers to death after a stroke that is either a direct consequence of the stroke or a complication of the stroke. Acute stroke should be verified to the extent possible by the diagnostic criteria outlined for stroke (See Definition of Transient Ischemic Attack and Stroke, for full details below).

Death Due to Cardiovascular Procedures:

refers to death caused by the immediate complications of a cardiac procedure.

Death Due to Cardiovascular Hemorrhage:

refers to death related to hemorrhage such as a non-stroke intracranial hemorrhage (see Definition of Transient Ischemic Attack and Stroke, for full details below), non-procedural or non-traumatic vascular rupture (e.g., aortic aneurysm), or hemorrhage causing cardiac tamponade.

Death Due to Other Cardiovascular Causes:

refers to a CV death not included in the above categories (e.g., pulmonary embolism or peripheral arterial disease).

Definition of Non-Cardiovascular Death:

Non-cardiovascular death is defined as any death that is not thought to be due to a cardiovascular cause. The following is a suggested list of non-cardiovascular causes of death for this trial.

-   -   Non-malignant, Non-cardiovascular Death:         -   Pulmonary;         -   Renal;         -   Gastrointestinal;         -   Hepatobiliary;         -   Pancreatic;         -   Infection (includes sepsis)         -   Non-infectious (e.g., systemic inflammatory response             syndrome (SIRS));         -   Hemorrhage that is neither cardiovascular bleeding nor a             stroke;         -   Accidental (e.g., physical accidents or drug overdoses) or             trauma;         -   Suicide; and/or         -   Prescription Drug Error (e.g., prescribed drug overdose, use             of inappropriate drug, or drug-drug interaction); and         -   Neurological process that is not a stroke or hemorrhage.     -   Malignancy: Malignancy is coded as cause of death, if:         -   Death results directly from the cancer; or         -   Death results from a concurrent illness that could be a             consequence of a cancer; or         -   Death results from withdrawal of other therapies because of             concerns relating to the poor prognosis associated with the             cancer; and         -   Death results from an illness that is not a consequence of a             cancer.

Cancer deaths may arise from cancers that were present prior to randomization or which developed subsequently. It may be helpful to distinguish these two scenarios (i.e. worsening of prior malignancy; new malignancy). Suggested categorization includes the following organ systems; Lung/larynx, breast, leukemia/lymphoma, upper GI, melanoma, central nervous system, colon/rectum, renal, bladder, prostate, other/unspecified, or unknown.

Definition of Undetermined Cause of Death:

refers to a death not attributable to one of the above categories of cardiovascular death or to a non-cardiovascular cause. The inability to classify the cause of death is generally due to lack of information (e.g., the only available information is “patient died”) or when there is insufficient supporting information or detail to assign the cause of death. In this trial, when a cause of death was not readily apparent (e.g., found dead at home), the cause was assumed to be cardiovascular in origin, unless one of the following two scenarios occur: there is no information or data available regarding the circumstances of death other than that a death has occurred; or the available data are conflicting regarding whether the death was cardiovascular or non-cardiovascular.

Definition of Myocardial Infarction:

The term myocardial infarction (MI) is used when there is evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. In general, the diagnosis of MI requires the combination of: evidence of myocardial necrosis (either changes in cardiac biomarkers or postmortem pathological findings); and supporting information derived from the clinical presentation, electrocardiographic changes, or the results of myocardial or coronary artery imaging.

The totality of the clinical, electrocardiographic, and cardiac biomarker information should be considered to determine whether or not a MI has occurred. Specifically, timing and trends in cardiac biomarkers and electrocardiographic information require careful analysis. The adjudication of MI should also take into account the clinical setting in which the event occurs. MI may be adjudicated for an event that has characteristics of a MI, but which does not meet the strict definition because biomarker or electrocardiographic results are not available.

The Criteria for myocardial infarction include clinical presentation, biomarker evaluation, and ECG changes.

Clinical Presentation:

The clinical presentation is consistent with diagnosis of myocardial ischemia and infarction. Other findings that might support the diagnosis of MI should be take into account because a number of conditions are associated with elevations in cardiac biomarkers (e.g., trauma, surgery, pacing, ablation, congestive heart failure, hypertrophic cardiomyopathy, pulmonary embolism, severe pulmonary hypertension, stroke or subarachnoid hemorrhage, infiltrative and inflammatory disorders of cardiac muscle, drug toxicity, burns, critical illness, extreme exertion, and chronic kidney disease). Supporting information can also be considered from myocardial imaging and coronary imaging. The totality of the data may help differentiate acute MI from the background disease process.

Biomarker Evaluation:

For cardiac biomarkers, laboratories should report an upper reference limit (URL). If the 99th percentile of the upper reference limit (URL) from the respective laboratory performing the assay is not available, then the URL for myocardial necrosis from the laboratory should be used. If the 99th percentile of the URL or the URL for myocardial necrosis is not available, the MI decision limit for the particular laboratory should be used as the URL. Laboratories can also report both the 99th percentile of the upper reference limit and the MI decision limit. Reference limits from the laboratory performing the assay are preferred over the manufacturer's listed reference limits in an assay's instructions for use. CK-MB and troponin are preferred, but CK may be used in the absence of CK-MB and troponin. For MI subtypes, different biomarker elevations for CK, CK-MB, or troponin were required. The specific criteria were referenced to the URL. In this study, patients may present acutely to hospitals which are not participating sites, it is not practical to stipulate the use of a single biomarker or assay, and the locally available results are to be used as the basis for adjudication. Since the prognostic significance of different types of myocardial infarctions (e.g., periprocedural myocardial infarction versus spontaneous myocardial infarction) may be different, considerations evaluating outcomes for these subsets of patients separately were made.

Ecg Changes:

ECG changes can be used to support or confirm a MI. Supporting evidence may be ischemic changes and confirmatory information may be new Q waves.

Criteria for acute myocardial ischemia (in absence of left ventricular hypertrophy (LVH) and left bundle branch block (LBBB)) include:

-   -   ST elevation: New ST elevation at the J point in two         anatomically contiguous leads with the cut-off points: ≥0.2 mV         in men (>0.25 mV in men <40 years) or ≥0.15 mV in women in leads         V2-V3 and/or ≥0.1 mV in other leads.     -   ST depression and T-wave changes new horizontal or down-sloping         ST depression ≥0.05 mV in two contiguous leads; and/or new T         inversion ≥0.1 mV in two contiguous leads.

The above ECG criteria illustrate patterns consistent with myocardial ischemia. In patients with abnormal biomarkers, it is recognized that lesser ECG abnormalities may represent an ischemic response and may be accepted under the category of abnormal ECG findings.

Criteria for pathological Q-wave include: any Q-wave in leads V2-V3 ≥0.02 seconds or QS complex in leads V2 and V3; Q-wave ≥0.03 seconds and ≥0.1 mV deep or QS complex in leads I, II, aVL, aVF, or V4-V6 in any two leads of a contiguous lead grouping (I, aVL, V6; V4-V6; II, III, and aVF); and R-wave 0.04 s in V1-V2 and R/S ratio >1 with a concordant positive T-wave in the absence of a conduction defect.

The same criteria are used for supplemental leads V7-V9, and for the Cabrera frontal plane lead grouping.

Criteria for Prior Myocardial Infarction include: pathological Q-waves, as defined above; and R-wave ≥0.04 seconds in V1-V2 and R/S≥1 with a concordant positive T-wave in the absence of a conduction defect.

Myocardial Infarction Subtypes:

Several MI subtypes are commonly reported in clinical investigations and each is defined below:

1. Spontaneous MI:

-   -   Detection of rise and/or fall of cardiac biomarkers with at         least one value above the URL with at least one of the         following:         -   Clinical presentation consistent with ischemia;         -   ECG evidence of acute myocardial ischemia;         -   New pathological Q waves;         -   Imaging evidence of new loss of viable myocardium or new             regional wall motion abnormality; and/or         -   Autopsy evidence of acute MI     -   If biomarkers are elevated from a prior infarction, then a         spontaneous myocardial infarction is defined as one of the         following:         -   Clinical presentation consistent with ischemia;         -   ECG evidence of acute myocardial ischemia;         -   New pathological Q waves;         -   Imaging evidence of new loss of viable myocardium or new             regional wall motion abnormality; and/or         -   Autopsy evidence of acute MI; and     -   Both of the Following:         -   Evidence that cardiac biomarker values were decreasing             (e.g., two samples 3-6 hours apart) prior to the suspected             MI (note: If biomarkers are increasing or peak is not             reached, then a definite diagnosis of recurrent MI is             generally not possible); and         -   ≥20% increase (and >URL) in troponin or CK-MB between a             measurement made at the time of the initial presentation and             a further sample taken 3-6 hours later.             2. Percutaneous Coronary Intervention-Related Myocardial             Infarction: is defined by any of the following criteria. MI             associated with and occurring within 48 hours of PCI, with             elevation of cardiac biomarker values to >5×99^(th)             percentile of the URL in patients with normal baseline             values (99^(th) percentile URL), or a rise of [cardiac             biomarker] values 20% if baseline values are elevated and             are stable or falling. This classification also requires at             least 1 of the following:     -   Symptoms suggestive of myocardial ischemia (i.e., prolonged         ischemia ≥20 min);     -   New ischemic changes on ECG or new LBBB;     -   Angiographic loss of patency of a major coronary artery or a         side branch or persistent slow flow or no flow or embolization;         and/or     -   Imaging evidence of new loss of viable myocardium or new         regional wall motion abnormality.         3. Coronary Artery Bypass Grafting-Related (CABG) Myocardial         Infarction: is defined by the following criteria. Symptoms of         cardiac ischemia were not required and data was collected in         such a way that analyses using 20% or 50% could both be         performed.     -   Biomarker elevations within 48 hours of CABG:         -   Troponin or CK-MB (preferred) >10×99^(th) percentile of the             URL; and         -   No evidence that cardiac biomarkers were elevated prior to             the procedure; or         -   Both of the following are true:             -   ≥50% increase in the cardiac biomarker result; and             -   Evidence that cardiac biomarker values were decreasing                 (e.g., two samples 3-6 hours apart) prior to the                 suspected MI; and     -   One of the following are true:         -   New pathological Q-waves persistent through 30 days;         -   New persistent non-rate-related LBBB;         -   Angiographically documented new graft or native coronary             artery occlusion Other complication in the operating room             resulting in loss of myocardium; or         -   Imaging evidence of new loss of viable myocardium.     -   Autopsy evidence of acute MI.         4. Silent Mvocardial Infarction: is defined by the following:     -   No evidence of acute myocardial infarction; and     -   Any one of the following criteria:         -   New pathological Q-waves. A confirmatory ECG is recommended             if there have been no clinical symptoms or history of             myocardial infarction;         -   Imaging evidence of a region of loss of viable myocardium             that is thinned and fails to contract, in the absence of a             non-ischemic cause; and/or         -   Autopsy evidence of a healed or healing MI.

In the case of evanescent 0 waves, the last ECG determines whether a silent infarction has occurred.

Sub-Classification of Myocardial Infarction:

The universal MI definition includes clinical classification of different types of MI, electrocardiographic features, and by biomarker evaluation, with the definition of each provided below.

Clinical Classification of Different Types of Myocardial Infarction include the following:

-   -   Type 1: Spontaneous myocardial infarction related to ischemia         due to a primary coronary event such as plaque erosion and/or         rupture, fissuring, or dissection;     -   Type 2: Myocardial infarction secondary to ischemia due to         either increased oxygen demand or decreased supply, e.g.,         coronary artery spasm, coronary embolism, anemia, arrhythmias,         hypertension, or hypotension;     -   Type 3: Sudden unexpected cardiac death, including cardiac         arrest, often with symptoms suggestive of myocardial ischemia,         accompanied by presumably new ST elevation, or new LBBB, or         evidence of fresh thrombus in a coronary artery by angiography         and/or at autopsy, but death occurring before blood samples         could be obtained, or at a time before the appearance of cardiac         biomarkers in the blood;     -   Type 4a: Myocardial infarction associated with Percutaneous         Coronary Intervention (PCI);     -   Type 4b: Myocardial infarction associated with stent thrombosis         as documented by angiography or at autopsy;     -   Type 4c: Myocardial infarction associated with stent restenosis         as detected by angiography or at autopsy; and     -   Type 5: Myocardial infarction associated with CABG.

By Electrocardiographic Features include:

-   -   ST-Elevation MI (STEMI). The additional categories of STEMI         include: Q wave, non-Q-wave, or unknown (no ECG or ECG         non-interpretable);     -   Non-ST-Elevation MI (NSTEMI). The additional categories NSTEMI         may include: Q wave, non-Q-wave, or unknown (no ECG or ECG         non-interpretable); and     -   Unknown (no ECG or ECG not interpretable).

All events adjudicated as MI were classified as STEMI, NSTEMI, or Unknown; however, it is acknowledged that a significant proportion of periprocedural (PCI or CABG) events may have missing, inadequate or uninterpretable ECG documentation.

By Biomarker Elevation (per Universal MI Definition): The magnitude of cardiac biomarker elevation can be calculated as a ratio of the peak biomarker value divided by the 99th percentile URL. The biomarker elevation can be provided for various MI subtypes.

Definition of Hospitalize of Unstable Angina:

Unstable angina requiring hospitalization is defined as:

-   -   Ischemic discomfort (angina, or symptoms thought to be         equivalent) ≥10 minutes in duration occurring at rest or in an         accelerating pattern with frequent episodes associated with         progressively decreased exercise capacity;     -   Prompting an unscheduled hospitalization within 24 hours of the         most recent symptoms. Hospitalization is defined as an admission         to an inpatient unit or a visit to an emergency department that         results in at least a 24-hour stay (or a date change if the time         of admission/discharge is not available); and     -   At least one of the following:         -   New or worsening ST or T wave changes on resting ECG (in             absence of confounders, such as LBBB or LVH);             -   Transient ST elevation (duration <20 minutes): New ST                 elevation at the J point in two anatomically contiguous                 leads with the cut-off points: ≥0.2 mV in men (≥0.25 mV                 in men <40 years) or ≥0.15 mV in women in leads V2-V3                 and/or 0.1 mV in other leads             -   ST depression and T-wave changes: New horizontal or                 down-sloping ST depression 0.05 mV in two contiguous                 leads; and/or new T inversion ≥0.1 mV in two contiguous                 leads.         -   Definite evidence of inducible myocardial ischemia as             demonstrated by:             -   An early positive exercise stress test, defined as ST                 elevation or 2 mm ST depression prior to 5 mets; or at                 least one of the following: stress echocardiography                 (reversible wall motion abnormality); myocardial                 scintigraphy (reversible perfusion defect); or MRI                 (myocardial perfusion deficit under pharmacologic                 stress.         -   Angiographic evidence of new or worse 70% lesion and/or             thrombus in an epicardial coronary artery that is believed             to be responsible for the myocardial ischemic             symptoms/signs; and         -   Need for coronary revascularization procedure (PCI or CABG)             for the presumed culprit lesion(s). This criterion would be             fulfilled if revascularization was undertaken during the             unscheduled hospitalization, or subsequent to transfer to             another institution without interceding home discharge;     -   Negative cardiac biomarkers and no evidence of acute MI.

General Considerations include:

Escalation of pharmacotherapy for ischemia, such as intravenous nitrates or increasing dosages of β-blockers, should be considered supportive of the diagnosis of unstable angina. However, a typical presentation and admission to the hospital with escalation of pharmacotherapy, without any of the additional findings listed under category 3, would be insufficient alone to support classification as hospitalization for unstable angina.

If subjects were admitted with suspected unstable angina, and subsequent testing revealed a noncardiac or non-ischemic etiology, this event should not have been recorded as hospitalization for unstable angina. Potential ischemic events meeting the criteria for myocardial infarction should not have been adjudicated as unstable angina.

Planned hospitalization or re-hospitalization for performance of an elective revascularization in patients who did not fulfill the criteria for unstable angina should not have been considered a hospitalization for unstable angina. For example: hospitalization of a patient with stable exertional angina for coronary angiography and PCI that is prompted by a positive outpatient stress test should not be considered hospitalization for unstable angina; or re-hospitalization of a patient meeting the criteria for unstable angina who was stabilized, discharged, and subsequently readmitted for revascularization, does not constitute a second hospitalization for unstable angina.

A patient who underwent an elective catheterization where incidental coronary artery disease was found and who subsequently underwent coronary revascularization was not be considered as meeting the hospitalization for unstable angina endpoint.

Transient Ischemic Attack:

Transient ischemic attack (TIA) is defined as a transient episode (<24 hours) of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction.

Stroke:

Stroke is defined as an acute episode of neurological dysfunction caused by focal or global brain, spinal cord, or retinal vascular injury.

Ischemic Stroke:

Ischemic stroke is defined as an acute episode of focal cerebral, spinal, or retinal dysfunction caused by an infarction of central nervous system tissue. Hemorrhage may be a consequence of ischemic stroke. In this situation, the stroke is an ischemic stroke with hemorrhagic transformation and not a hemorrhagic stroke.

Hemorrhagic Stroke:

Hemorrhagic stroke is defined as an acute episode of focal or global cerebral or spinal dysfunction caused by a nontraumatic intraparenchymal, intraventricular, or subarachnoid hemorrhage. However, microhemorrhages seen on T2-weighted MRI imaging, subdural and epidural hemorrhages are not considered hemorrhagic strokes.

Undetermined Stroke:

Undetermined stroke is defined as an acute episode of focal or global neurological dysfunction caused by presumed brain, spinal cord, or retinal vascular injury as a result of hemorrhage or infarction but with insufficient information to allow categorization as ischemic or hemorrhagic.

Stroke Disability:

Stroke disability should be measured by a reliable and valid scale in all cases, typically at each visit and 90 days after the event. For example, the modified Rankin Scale show below in Table 13 may be used to address this requirement:

TABLE 13 Rankin Scaled Used to Assess Stroke Disability in Patients Scale Disability 0 No symptoms at all. 1 No significant disability despite symptoms; able to carry out all usual duties and activities. 2 Slight disability, unable to perform all previous activities but able to look after own affairs without assistance. 3 Moderate disability; requiring some help but able to walk without assistance. 4 Moderately severe disability, unable to walk without assistance and unable to attend to own bodily needs without assistance. 5 Severe disability, bedridden, incontinent, and requiring constant nursing and attention. 6 Dead

Additional Considerations: Evidence of vascular central nervous system injury without recognized neurological dysfunction may be observed. Examples include micro-hemorrhage, silent infarction, and silent hemorrhage. Subdural hematomas are intracranial hemorrhagic events and not strokes. The distinction between a Transient Ischemic Attack and an Ischemic Stroke is the presence of Infarction. Persistence of symptoms is an acceptable indicator of acute infarction.

Definition of Heart Failure Event:

is defined as an event that meets all of the following criteria:

-   -   The patient is admitted to the hospital with a primary diagnosis         of HF;     -   The patient's length-of-stay in hospital extends for at least 24         hours (or a change in calendar date if the hospital admission         and discharge times are unavailable);     -   The patient exhibits documented new or worsening symptoms due to         HF on presentation, including at least one of the following:         dyspnea (dyspnea with exertion, dyspnea at rest, orthopnea,         paroxysmal nocturnal dyspnea), decreased exercise tolerance,         fatigue, or other symptoms of worsened end-organ perfusion or         volume overload (must be specified and described by the         protocol);     -   The patient has objective evidence of new or worsening HF,         consisting of at least two physical examination findings or one         physical examination finding and at least one laboratory         criterion), including:         -   Physical examination findings considered to be due to heart             failure, including new or worsened: Peripheral edema,             increasing abdominal distention or ascites (in the absence             of primary hepatic disease), S₃ gallop, clinically             significant or rapid weight gain thought to be related to             fluid retention; or         -   Laboratory evidence of new or worsening HF, if obtained             within 24 hours of presentation, including: increased B-type             natriuretic peptide (BNP)/N-terminal pro-BNP (NT-proBNP)             concentrations consistent with decompensation of heart             failure (such as BNP >500 pg/mL or NT-proBNP >2,000 pg/mL).             In patients with chronically elevated natriuretic peptides,             a significant increase should be noted above baseline,             radiological evidence of pulmonary congestion, or             non-invasive or invasive diagnostic evidence of clinically             significant elevated left- or right-sided ventricular             filling pressure or low cardiac output. For example,             echocardiographic criteria could include: E/e′>15 or             D-dominant pulmonary venous inflow pattern, plethoric             inferior vena cava with minimal collapse on inspiration, or             decreased left ventricular outflow tract (LVOT) minute             stroke distance (time velocity integral [TVI]) OR right             heart catheterization showing a pulmonary capillary wedge             pressure (pulmonary artery occlusion pressure) ≥18 mmHg,             central venous pressure ≥12 mmHg, or a cardiac index <2.2             L/min/m².     -   The patient receives initiation or intensification of treatment         specifically for HF, including at least one of the following:         significant augmentation in oral diuretic therapy, intravenous         diuretic, inotrope, or vasodilator therapy, or Mechanical or         surgical intervention. The mechanical or surgical intervention         including mechanical circulatory support (e.g., intra-aortic         balloon pump, ventricular assist device) and/or mechanical fluid         removal (e.g., ultrafiltration, hemofiltration, dialysis).

New Heart Failure/Heart Failure not Requiring Hospitalization:

is defined as an event that meets all of the following: the patient has an urgent, unscheduled office/practice or emergency department visit for a primary diagnosis of HF, but not meeting the criteria for a HF hospitalization; all signs and symptoms for HF hospitalization must be met as defined in A Heart Failure Hospitalization above; and the patient receives initiation or intensification of treatment specifically for HF, as detailed in the above section with the exception of oral diuretic therapy, which was not sufficient.

Interventional Cardiology Definitions

Clinical Definitions:

Clinically-Driven Target Lesion Revascularization:

Revascularization is clinically-driven if the target lesion diameter stenosis is >50% by quantitative coronary angiography (QCA) and the subject has clinical or functional ischemia which cannot be explained by another native coronary or bypass graft lesion. Clinical or functional ischemia includes any of the following: a history of angina pectoris, presumably related to the target vessel; objective signs of ischemia at rest (electrocardiographic changes) or during exercise test (or equivalent), presumably related to the target vessel; and abnormal results of any invasive functional diagnostic test (e.g., coronary flow reserve [CFR] or fractional flow reserve [FFR]).

Non-Target Lesion and Non-Target Lesion Revascularization:

A lesion for which revascularization is not attempted or one in which revascularization is performed using a non-study device, respectively.

Non-Target Vessel and Non-Target Vessel Revascularization:

A vessel for which revascularization is not attempted or one in which revascularization is performed using a non-study device, respectively.

Percutaneous Coronary Intervention (PCI) Status includes:

-   -   Elective: The procedure can be performed on an outpatient basis         or during a subsequent hospitalization without significant risk         of myocardial infarction (MI) or death. For stable in-patients,         the procedure is being performed during this hospitalization for         convenience and ease of scheduling and NOT because the patient's         clinical situation demands the procedure prior to discharge.     -   Urgent: The procedure should be performed on an inpatient basis         and prior to discharge because of significant concerns that         there is risk of myocardial ischemia, MI, and/or death. Patients         who are outpatients or in the emergency department at the time         that the cardiac catheterization is requested would warrant         hospital admission based on their clinical presentation.     -   Emergency: The procedure should be performed as soon as possible         because of substantial concerns that ongoing myocardial ischemia         and/or MI could lead to death. “As soon as possible” refers to a         patient who is of sufficient acuity that one would cancel a         scheduled case to perform this procedure immediately in the next         available room during business hours, or one would activate the         on-call team were this to occur during off-hours.

Salvage: The procedure is a last resort. The patient is in cardiogenic shock when the PCI begins (i.e., the time at which the first guide wire or intracoronary device is introduced into a coronary artery or bypass graft for the purpose of mechanical revascularization) or within the last ten minutes prior to the start of the case or during the diagnostic portion of the case, the patient has also received chest compressions or has been on unanticipated circulatory support (e.g., intra-aortic balloon pump, extracorporeal mechanical oxygenation, or cardiopulmonary support).

Percutaneous Coronary Intervention (PCI):

Placement of an angioplasty guide wire, balloon, or other device (e.g., stent, atherectomy catheter, brachytherapy delivery device, or thrombectomy catheter) into a native coronary artery or coronary artery bypass graft for the purpose of mechanical coronary revascularization. In the assessment of the severity of coronary lesions with the use of intravascular ultrasound, CFR, or FFR, insertion of a guide wire was not considered PCI.

Peripheral Vascular Intervention Definitions:

Peripheral Vascular Intervention Definition:

Peripheral vascular intervention is a catheter-based or open surgical procedure designed to improve peripheral arterial or venous blood flow or otherwise modify or revise vascular conduits. Procedures may include, but are not limited to, balloon angioplasty, stent placement, thrombectomy, embolectomy, atherectomy, dissection repair, aneurysm exclusion, treatment of dialysis conduits, placement of various devices, intravascular thrombolysis or other pharmacotherapies, and open surgical bypass or revision. In general, the intention to perform percutaneous peripheral vascular intervention is denoted by the insertion of a guide wire into a peripheral artery or vein. The target vessel(s) and the type of revascularization procedure (e.g., surgical bypass, thrombectomy, endarterectomy, percutaneous angioplasty, stent placement, thromboembolectomy, and thrombolysis) should be specified and recorded. For the sake of simplicity, this definition applies to the extracranial carotid artery and other non-cardiac arteries and veins and excludes the intracranial vessels and lymphatics.

Procedural Status includes:

-   -   Non-Elective: Non-elective procedures include emergent and         urgent procedures. A non-elective procedure is a procedure that         is performed without delay, because there is clinical consensus         that the procedure should occur imminently. Non-elective         procedures imply a degree of instability of the patient, urgency         of the medical condition, or instability of the threatening         lesion.         -   Emergent: A procedure that is performed immediately because             of the acute nature of the medical condition (e.g., acute             limb ischemia, acute aortic dissection), and the increased             morbidity or mortality associated with a temporal delay in             treatment.         -   Urgent: An urgent procedure is one that is not emergent but             required to be performed on a timely basis (≤24 hrs) (e.g.,             a patient who has been stabilized following initial             treatment of acute limb ischemia, and there is clinical             consensus that a definitive procedure should occur within             the next 24 hours).     -   Elective: An elective procedure is one that is scheduled and is         performed on a patient with stable disease, or in whom there is         no urgency and/or increased morbidity or mortality associated         with a planned procedure.

Definition of Any Revascularization Procedure:

Any revascularization includes any arterial vascular intervention done to treat ischemia or prevent major ischemic events, including percutaneous or surgical intervention of the coronary, peripheral, or carotid arteries. Aneurysm repairs, dissection repairs, arterial-venous fistula or graft placement or repairs, or renal arterial intervention for hypertension or renal dysfunction are not included.

Definition of Cardiac Arrhythmia Requiring Hospitalization:

An arrhythmia that either results in hospitalization (≥24 hours) during or within 24 hours of the termination of the last episode for treatment or requires continued hospitalization for treatment, including any one of the following:

-   -   Atrial arrhythmia—atrial fibrillation, atrial flutter,         supraventricular tachycardia that requires cardio-version, drug         therapy, or is sustained for greater than 1 minute;     -   Ventricular arrhythmia—Ventricular tachycardia or ventricular         fibrillation requiring cardio-version and/or intravenous         antiarrhythmics; and/or     -   Bradyarrhythmia—High-level AV block (defined as third-degree AV         block or second-degree AV block), junctional or ventricular         escape rhythm, or severe sinus bradycardia (typically with heart         rate <30 bpm). The bradycardia must require temporary or         permanent pacing.

Definition of Cardiac Arrest (Sudden Cardiac Death):

A sudden, unexpected death due to the cessation of cardiac mechanical activity, confirmed by the absence of a detectable pulse, unresponsiveness, and apnea (or agonal, gasping respirations) of presumed cardiac etiology. An arrest is presumed to be cardiac (i.e., related to heart disease) if this is likely, based on the available information, including hospital records and autopsy data. The cardiac arrest is further sub-classified into either: witnessed, occurring within 60 min from the onset of new symptoms, in the absence of a clear cause other than cardiovascular; or unwitnessed, within 24 hours of being observed alive, in the absence of pre-existing other non-cardiovascular causes of death;

Non-cardiac causes of cardiac arrest, such as drug overdose, suicide, drowning, hypoxia, exsanguination, cerebrovascular accident, subarachnoid hemorrhage, or trauma must not be present.

Definition of Resuscitated Cardiac Arrest:

Resuscitated Cardiac Arrest is present when there is restoration of both: organized electrical activity and organized mechanical activity resulting in restoration of spontaneous circulation (defined as the documented presence of a measurable pulse and blood pressure at any time after initiation of resuscitative efforts).

Criteria for the Diagnosis of Metabolic Syndrome:

The diagnosis of metabolic syndrome requires the presence of three out of the following five specific components using the following criteria with cut points of parameters as defined in Table 1 and listed below, and waist circumference cut points further guided by the Table 14.

-   -   A waist circumference ≥35 inches (88 cm) for all women, and         Asian, Hispanic, or Latino men, and waist circumference ≥40         inches (102 cm) for all other men;     -   Elevated TG (TG ≥150 mg/dL);     -   Reduced HDL-C(HDL-C <40 mg/dL if male; HDL-C <50 mg/dL if         female);     -   Elevated blood pressure (systolic ≥130 mmHg and/or diastolic 285         mmHg, or an antihypertensive therapy with medical history of         hypertension; and     -   Elevated fasting glucose (fasting glucose 2100 mg/dL, or on drug         therapy for elevated glucose.

Statistical Analysis

In this event-driven trial, it was estimated that approximately 1612 adjudicated primary endpoint events would be necessary to provide 90% power to detect a 15% lower risk of the primary composite endpoint in the AMR101 group than in the placebo group. This resulted in an estimated sample size of approximately 7990 patients to reach the number of primary endpoints. The primary efficacy analysis was based on the time from randomization to the first occurrence of any component of the primary composite endpoint. If the relative risk reduction with administration of AMR101 in the primary endpoint was significant (final two-sided alpha level=0.0437; determined from O'Brien-Fleming boundaries generated using the Lan-DeMets alpha-spending function after accounting for two protocol pre-specified interim efficacy analyses), in a hierarchical fashion, the key secondary endpoint and other prespecified secondary endpoints were to be tested at the same final alpha level of 0.0437. All primary efficacy analyses followed the intent-to-treat principle. HRs and 95% CI were generated using a Cox proportional hazard model with treatment as covariate, and stratified by cardiovascular risk category, geographic region, and use of ezetimibe. Log-rank P values were reported from a Kaplan-Meier analysis, stratified by the three randomization factors, to evaluate the timing of events in the two treatment groups.

Results

Subject Disposition:

The subject disposition by treatment group is depicted in FIG. 2. A total of 19,212 patients were screened of whom 8,179 (43%) were randomized. At the time of database lock, vital status was available in 99.8%; 152 (1.9%) patients did not complete final study visits and 578 (7.1%) patients withdrew consent. Demographic and Baseline Disease Characteristics: Among the patients who underwent randomization, 70.7% were enrolled on the basis of secondary prevention (i.e., patients had established cardiovascular disease) and 29.3% for primary prevention (i.e., patients had diabetes mellitus and at least one additional risk factor). The median age was 64 years, 28.8% were female, and 38.5% were from the United States. At baseline, the median LDL-cholesterol was 75.0 mg/dL, HDL-cholesterol was 40.0 mg/dL, and triglycerides were 216.0 mg/dL.

The baseline LDL-C value obtained via Preparative Ultracentrifugation was used, unless this value was missing. If the LDL-C Preparative Ultracentrifugation value was missing, then another LDL-C value was be used, with prioritization of values obtained from LDL-C Direct measurements, followed by LDL-C derived by the Friedewald calculation (only for patients with TG <400 mg/dL), and finally LDL-C derived using the calculation published by Johns Hopkins University investigators.22 At Visit 1 and Visit 1.1 Direct LDL-C was used if at the same visit TG >400 mg/dL At alll remaining visits LDL-C was measured by Direct LDL-C or by Preparative Ultracentrifugation if at the same visit TG >400 mg/dL. For all other lipid and lipoprotein marker parameters, wherever possible, baseline was derived as the arithmetic mean of the Visit 2 (Day 0) value and the preceding Visit 1 (or Visit 1.1) value. If only one of these values was available, the single available value was used as baseline. The only significant baseline between group difference with p < 0.05 was LDL-C (p = 0.03). ^([1])Race as reported by the investigators. ^([2])Westernized region includes Australia; Canada, Netherlands, New Zealand, United States, and South Africa. ^([3])Eastern European region includes Poland; Romania, Russian Federation, and Ukraine. ^([4])Asia Pacific region includes India.

The median trial follow-up duration was 4.9 years with a maximum of 6.2 years. The median change in triglycerides from baseline to one year was −18.3% (−39.0 mg/dL) in the AMR101 group and +2.2% (4.5 mg/dL) in the placebo group; the median reduction from baseline (as estimated with the use of the Hodges-Lehmann approach) was 19.7% greater in the AMR101 group than in the placebo group (a 44.5 mg/dL [0.50 mmol/L] greater reduction; P<0.001). The median change in LDL cholesterol level from baseline was an increase of 3.1% (2.0 mg/dL [0.05 mmol/L]) in the AMR101 group and an increase of 10.2% (7.0 mg/dL [0.18 mmol/L]) in the placebo group—a 6.6% (5.0 mg/dL [0.13 mmol/L]) lower increase with AMR101 than with placebo (P<0.001).

Analyses of Primary Composite Endpoint:

There were a total of 1606 adjudicated primary endpoint first events. FIG. 3A shows the Kaplan-Meier event curves for the primary efficacy endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina in the AMR101 and placebo groups with the inset showing the data on an expanded y axis. All patients were included in the analysis and patients experiencing more than one type of endpoint event were counted for their first occurrence in each event type. The primary endpoint as shown in FIG. 3A occurred in 17.2% of AMR101 patients versus in 22.0% of placebo patients (HR, 0.75; 95% CI, 0.68-0.83; P<0.001) for an absolute risk reduction (AAR) of 4.8% (95% CI, 3.1-6.5%) and number needed to treat (NNT) of 21 (95% CI, 15-33) over median follow up 4.9 years. Similarly, FIG. 3B shows the Kaplan-Meier estimates of the cumulative incidence of the primary composition endpoints over time. Significantly, FIG. 3B indicates a 25% relative risk reduction for the primary composite endpoint over the course of 5 years.

FIG. 4 lists the individual components of the primary endpoint analyzed as time to first event of each individual endpoint. Shown first in FIG. 4 is the HR and 95% CI for the primary composite endpoint event (time to first occurrence of either cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina). Shown separately beneath FIG. 4 are HRs and 95% CIs for time to first occurrence of each type of individual primary endpoint component event, irrespective of whether contributing to the primary composite endpoint event or not.

Analyses of Key Secondary Endpoints:

FIG. 5A shows the Kaplan-Meier event curves for the key secondary efficacy endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke in the AMR101 and placebo groups with the inset showing the data on an expanded y axis. All patients were included in the analysis and patients experiencing more than one type of endpoint event were counted for their first occurrence in each event type. The key secondary efficacy endpoint as shown in FIG. 5A occurred in 11.2% of AMR101 patients versus 14.8% of placebo patients (HR, 0.74, 95% CI 0.65-0.83, P<0.001) for an absolute risk reduction of 3.6% (95% CI, 2.1-5.0%) and a number needed to treat of 28 (95% CI, 20-47) over median follow up 4.9 years. Similarly, FIG. 5B shows the Kaplan-Meier estimates of the cumulative incidence of the key secondary composition endpoints over time. Significantly, FIG. 5B indicates a 26% relative risk reduction for the key secondary composite endpoint over the course of 5 years.

Analysis of Prespecified Subgroups

The primary efficacy outcomes in select prespecified subgroups are shown in FIGS. 6 and 7 with corresponding HRs and 95% CIs for the primary efficacy endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina from select prespecified subgroups in the AMR101 and placebo groups. The key secondary efficacy outcomes in select prespecified subgroups are shown in FIGS. 8 and 9 with corresponding HRs and 95% CIs for the key secondary efficacy endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina from select prespecified subgroups in the AMR101 and placebo groups. Significantly, FIGS. 6-9 indicate that a subject's baseline triglyceride levels (e.g., ≥150 vs. <150 mg/dL or ≥200 or <200 mg/dL) had no influence on the primary or key secondary efficacy endpoints.

This conclusion is further substantiated by the combination of FIGS. 10A and 10B which show that achievement of on-treatment triglyceride levels above or below 150 mg/dL at one year did not influence the efficacy of AMR101 versus placebo. In particular, FIGS. 10A and 10B show the primary and key secondary endpoints by achieved triglyceride level (e.g., above or below 150 mg/dL) at 1 year (e.g., patients with a triglyceride level above or below 150 mg/dL after 1 year of having received the AMR101). FIG. 10A are the Kaplan-Meier curves for the primary endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina in the AMR101 treatment group for patients with achieved triglycerides, and the placebo group at year 1. Conversely, FIG. 10B are the Kaplan-Meier event curves for the key secondary endpoint of time to first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke in the AMR101 treatment group for patients with achieved triglycerides, and the placebo group at year 1. Importantly, FIGS. 10A and 10B indicate that regardless of the subject's triglyceride levels at year 1, the subject experienced a statistically significant reduction in time to first occurrence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina. The attainment of triglyceride levels of 150 mg/dL or higher or below 150 mg/dL at 1 year after randomization also had no influence on the efficacy of AMR101 as compared with placebo with respect to the primary or key secondary efficacy endpoint. In a post hoc analysis, no substantial difference in the benefit of AMR101 as compared with placebo was observed with respect to the primary endpoint according to whether the patients who received placebo had an increase in LDL cholesterol levels at 1 year or had no change or a decrease in LDL cholesterol levels.

FIG. 11 depicts the prespecified hierarchical testing of the endpoints; except for the last hierarchical secondary endpoint of death from any cause (also referred to as total mortality), all other individual and composite ischemic endpoints were significantly reduced by AMRI01, including cardiovascular death (4.3% versus 5.2%; HR, 0.80; 95% CI, 0.66-0.98; P=0.03). Total mortality was 6.7% versus 7.6% (HR, 0.87; 95% CI, 0.74-1.02; P=0.09) in the AMR101 and placebo groups, respectively. For each of the prespecified endpoints in FIG. 11, icosapent ethyl 4 g per day provide a RRR of 25% for the primary composite endpoint, 26% for the secondary composite endpoint, 25% for the composite of cardiovascular death or nonfatal myocardial infarction, 31% for fatal or nonfatal myocardial infarction, 35% for urgent or emergent revascularization, 20% for cardiovascular death, 32% for hospitalization for unstable angina, 28% for fatal or nonfatal stroke, 23% reduction in the composite of total mortality, nonfatal myocardial infarction, or nonfatal stroke, and lastly, a 13% reduction in total mortality.

Results for selected tertiary outcomes are shown in Table 17. A tertiary endpoint, adjudicated sudden cardiac death was 2.1% versus 1.5% (HR, 0.69; 95% CI, 050-0.96).

Adverse events occurring in ≥5% are reported in Table 22. Compared with placebo, AMR101 was associated with a significantly higher rate of atrial fibrillation (5.3% versus 3.9%), and peripheral edema (6.5% vs 5%), but a lower rate of diarrhea (9% vs 11.1%), anemia (4.7% vs 5.8%), and gastrointestinal adverse events (33.0% to 35.1%). There was no significant difference in the prespecified adjudicated tertiary endpoint of heart failure (4.1% vs 4.3%). The prespecified adjudicated tertiary endpoint of atrial fibrillation or flutter requiring hospitalization was more common with the AMR101 group than the placebo group (3.1% vs 2.1%; P=0.004).

Among the 8,179 patients (70.7% secondary prevention) followed for a median 4.9 years, the primary endpoint occurred in 17.2% of AMR101 patients versus 22.0% of placebo (HR, 0.75; 95% CI, 0.68-0.83; P<0.001) and the key secondary endpoint in 11.2% versus 14.8% (HR, 0.74; 95% CI, 0.65-0.83; P<0.001). Additional ischemic endpoints, assessed according to a prespecified hierarchical schema, were significantly reduced, including cardiovascular death (4.3% versus 5.2%; HR, 0.80; 95% CI, 0.66-0.98; P=0.03). Atrial fibrillation or flutter hospitalization was more common with the AMR101 patients than the placebo patients (3.1% versus 2.1%; P=0.004); serious bleeding occurred in 2.7% of the AMR101 patients versus 2.1% in the placebo patients (P=0.06). There were no significant differences between treatments in the overall rate of treatment emergent adverse events or serious adverse events leading to withdrawal of study drug as shown in Table 20. The only serious adverse event occurring at a frequency 2% was pneumonia at 2.6% in the AMR101 group versus 2.9% in the placebo group (P=0.42).

Conclusion

In this study, the risk of the primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina, assessed in a time-to-event analysis, was significantly lower, by 25%, among the patients who received 2 g of icosapent ethyl twice daily than among those who received placebo, corresponding to an absolute between-group difference of 4.8 percentage points in the rate of the endpoint and a number needed to treat of 21. The risk of the key secondary composite endpoint of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke in a time-to-event analysis was also significantly lower, by 26%, in patients who received 2 g of icosapent ethyl twice daily than among those who received placebo, corresponding to an absolute between-group difference of 3.6 percentage points in the rate of the endpoint and a number needed to treat of 28. Prespecified hierarchical testing of other secondary endpoints revealed that the risks of a variety of fatal and nonfatal ischemic events were lower in the AMR101 group than in the placebo group, including a 20% lower risk of cardiovascular death. The benefits were observed against a background of appropriate statin use among patients who had a median LDL cholesterol level of 75.0 mg/dL at baseline.

Overall adverse event rates were similar across treatment groups. There were numerically more serious adverse events related to bleeding, though overall rates were low, with no fatal bleeding observed in either group and no significant increase in adjudicated hemorrhagic stroke or serious central nervous system or gastrointestinal bleeding. There was a significantly higher rate of hospitalization for atrial fibrillation or flutter, though rates were low in those patients who received 2 g of icosapent ethyl twice daily. Adverse event and serious adverse event rates leading to study drug discontinuation were similar to placebo. The rates of adverse events and serious adverse events leading to discontinuation of trial drug were similar in the two groups.

The results from this study stand apart from the negative findings of several recent trials of other agents that also lower triglyceride levels, such as other omega-3 fatty acids, extended-release niacin, fenofibrate, and cholesteryl ester transfer protein-inhibitors. It is not known whether the lack of benefit of omega-3 fatty acids in previous trials might be attributable to the low dose or the low ratio of EPA to DHA. Both the formulation (a highly purified and stable EPA acid ethyl ester) and dose (4 grams daily) used in this study are different from all prior omega-3 outcome trials. Despite utilizing a standard PROBE design limitation of those previous trials included an open label design without placebo, use of a low-intensity statin, and conducted in a single country; in contrast to the present report, patients in those trials had higher baseline LDL-C levels (182 mg/dL prior to statin initiation) and lower triglyceride values (151 mg/dL). In contrast, the present study provides robust, multinational data showing significant reductions in ischemic events with administration of icosapent ethyl in patients with well-controlled LDL-C. Metabolic data support that icosapent ethyl does not raise LDL cholesterol levels, which DHA containing formulations do.

A triglyceride level ≥150 mg/dL was required for inclusion in this study however, owing to initial allowance for variability in these levels and differences between qualifying and randomization measurements, 10.3% of enrolled patients had triglycerides less than 150 mg/dL on study entry. Cardiovascular benefits appeared similar across baseline levels of triglycerides (e.g., 135-149, 150 to 199, and 200 mg/dL or greater). Additionally, the robust reduction in major adverse cardiovascular events with administration of icosapent ethyl appeared to occur irrespective of an achieved triglyceride level above or below 150 mg/dL at one year, suggesting that the cardiovascular risk reduction was not tied to achieving a more normal (i.e., <150 mg/dL) triglyceride level. These observations suggest that at least some of the impact of icosapent ethyl on the reduction in ischemic events may be explained by metabolic effects other than triglyceride lowering.

Mechanisms responsible for the benefit in the present study are currently not known. The timing of divergence of the Kaplan-Meier event curves suggests a delayed onset to benefit, which may reflect the time to benefit from triglyceride reduction or other mechanisms. The modestly higher rate of bleeding suggests that there might be an anti-thrombotic mechanism of action. However, it is unlikely that an anti-thrombotic effect would reduce elective revascularization. Also, if the full explanation were an antiplatelet or anticoagulant effect, one might expect a large increase in major bleeding, which was not seen. Potentially, membrane-stabilizing effects could explain part of the benefit. Stabilization and/or regression of coronary plaque may also play a part. The observation in the present study of a lower rate of sudden cardiac death might support that mechanism, though this finding should be viewed as exploratory. It is also possible that the 40% reduction in hsCRP observed in patients from this trial may contribute to benefit. Samples (e.g., serum and plasma) from patients who participated in this trial have been banked for biomarker and genetic analyses, which may provide more information regarding mechanisms of action.

Regarding higher rates of diarrhea in the mineral oil placebo group, a post hoc analysis excluding patients with diarrhea still resulted in a significant risk reduction of 25% in the primary endpoint. Also, there were no differences in the primary or key secondary endpoints for placebo patients with an increase in LDL-C compared to those with no change or a decrease in LDL-C.

In conclusion, AMR101 4 grams daily demonstrated similar overall adverse event rates as placebo, and reduced important ischemic events, including cardiovascular death, in statin-treated patients with elevated triglycerides. Compared with placebo, icosapent ethyl 4 g per day significantly reduced cardiovascular events by 25% including: a 31% reduction in heart attack, 28% reduction in stroke, 31% reduction in myocardial infarction, and a 20% reduction in death due to cardiovascular events.

The following are key conclusions obtained from this trial that indicate a very favorable risk-benefit profile (1) significant reduction in primary endpoint with a RRR of 24.8%, ARR of 4.8%, NNT of 21, and a p-value of 0.00000001, (2) significant reduction in key secondary endpoint with a RRR of 26.5%, ARR of 3.6%, NNT of 28, and a p-value of 0.00000062, (3) consistent results across subgroups to include triglycerides and secondary and primary prevention, (4) consistent results across hierarchical secondary endpoints to include cardiovascular death, (5) consistent results across recurrent events, and (6) safety with a small but insignificant increase in atrial fibrillation/flutter with low event rates and non-significant increase in serious bleeding with low event rates.

Example 2: The Impact of Icosapent Ethyl on Recurrent Events and Total Ischemic Events in Statin-Treated Patients

Despite statin therapy, patients with established cardiovascular disease or diabetes remain at high risk for, not only first but also, recurrent ischemic events. The study results described in Example 1 demonstrated that icosapent ethyl reduces the first occurrence of the composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina, with a 25% relative risk reduction and a 4.8% absolute risk reduction. The time to first occurrence of the composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke was also reduced with icosapent ethyl, with a 26% relative risk reduction and a 3.6% absolute risk reduction.

The objective of the following study was to assess the impact of icosapent ethyl on recurrent events and total ischemic events. With a greater number of events, it was contemplated that there might be sufficient statistical power to examine the effect of icosapent ethyl in the two separate cardiovascular risk strata in the trial: patients with established atherosclerosis or patients with diabetes plus at least one other cardiovascular risk factor. Accordingly, the goal of the following study was to determine if icosapent ethyl administered at 4 g per day (e.g., 2 g twice daily) reduces total major adverse cardiovascular events in patients with fasting triglycerides 150 and <500 mg/dL and LDL-cholesterol >40 and ≤100 mg/dL who are at increased cardiovascular risk despite statin therapy.

Study Design

The following study was a multi-center, placebo-controlled clinical trial the details of which are described above in Example 1, the REDUCE-IT design. As shown in FIG. 12, patients were randomized in a double-blind manner to icosapent ethyl 4 g/day (2 grams twice daily with food) versus placebo. Randomization was stratified by cardiovascular risk cohort (i.e., secondary or primary prevention), use of ezetimibe, and by geographic region.

Study Population

The study participants included patients with a history of atherosclerosis or diabetes who were on statins and had fasting triglycerides ≥150 and <500 mg/dL and LDL-cholesterol >40 and ≤100 mg/dL. Of the study participants, 71% of the patients had a history of atherosclerosis and 29% had a history of diabetes. In order to be eligible for the trial, patients had to be ≥45 years of age with either established cardiovascular disease (i.e., secondary prevention stratum) or ≥50 years old with type 2 or type 1 diabetes mellitus requiring treatment with medication and at least one additional risk factor (i.e., primary prevention stratum).

The secondary prevention stratum consisted of patients with documented coronary artery disease (≥50% stenosis in at least two major epicardial coronary arteries with or without prior revascularization; prior MI; hospitalization for non-ST-segment elevation acute coronary syndrome with ST-segment deviation or positive biomarkers); documented cerebrovascular disease (prior ischemic stroke: symptomatic ≥50% carotid stenosis; asymptomatic carotid disease with ≥70% stenosis; history of carotid revascularization); or documented peripheral artery disease (ankle-brachial index <0.9 with symptoms of intermittent claudication; history of aorto-iliac or peripheral surgery or intervention).

The primary prevention stratum consisted of patients with no documented cardiovascular disease as defined above, with diabetes, and with at least one of the following cardiovascular risk factors: men ≥55 years of age or women ≥65 years of age; cigarette smoker or stopped smoking within 3 months before first visit; blood pressure ≥140 mmHg systolic or ≥90 mmHg diastolic or on antihypertensive medication; HDL-cholesterol ≤40 mg/dL for men or ≤50 mg/dL for women; hsCRP >3 mg/L; creatinine clearance >30 and <60 mL/min; non-proliferative retinopathy, pre-proliferative retinopathy, proliferative retinopathy, maculopathy, advanced diabetic eye disease or a history of photocoagulation; micro- or macro-albuminuria; or asymptomatic ankle-brachial index <0.9.

The participants were required to have fasting triglycerides between 150 mg/dL and <500 mg/dL and LDL-cholesterol >40 mg/dL and 100 mg/dL. In the initial version of the clinical trial protocol, a 10% allowance in qualifying triglyceride levels was allowed, and therefore patients with triglycerides 135 mg/dL were randomized. The study included 841 (10.3%) patients with baseline triglyceride levels <150 mg/dL. After approximately 60% of the patients were enrolled, an amendment changed the lower limit of allowed triglyceride levels to 200 mg/dL with no variability allowance. Patients were required to be on stable statin therapy for at least four weeks.

Exclusion criteria for the study participants included severe heart failure or liver disease, hemoglobin A1c levels >10.0%, planned coronary intervention, familial lipoprotein lipase deficiency, intolerance or hypersensitivity to statins, history of acute or chronic pancreatitis, and hypersensitivity to fish, shellfish, or ingredients of icosapent ethyl or placebo.

Main Outcomes and Measures

The primary outcome for the study was total recurrent events consisting of the composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina. Recurrent event analyses were also performed for the key secondary endpoint, a composite of cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke. For each of these composite endpoints, the effects of icosapent ethyl in the secondary and primary prevention strata were examined separately.

Statistical Considerations

Demographic and baseline disease characteristics are presented using frequencies and percentages for categorical variables and medians with interquartile ranges for continuous variables. Between treatment group comparisons were derived using the chi-square test for categorical variables and Wilcoxon rank test for continuous variables. All clinical endpoint events used in the efficacy analyses were adjudicated by an independent Clinical Endpoint Committee (CEC) who were blinded to the treatment assignment. Since the primary efficacy endpoint was the time from randomization to the first occurrence of any component of the composite endpoint, and recurrence of such events within each patient is possible, a pre-specified analysis using a Cox proportional-hazard with the counting-process formulation of Andersen and Gill was performed to model the first and all recurrent cardiovascular events. Hazard ratios (HR) and corresponding 95% confidence intervals (CI) are reported from this model. In addition, as a marginal model and an extension of survival models based on the Cox proportional hazard model, the modified Wei-Lin-Weissfeld (WLW) method for analysis of recurrent events in the presence of deaths was carried out as a supportive analysis. In addition, as pre-specified, a recurrent event analysis using the Andersen-Gill and Wei-Lin-Weissfeld methods were carried out for the individual primary event components other than CV death. Though not pre-specified, additional recurrent event analyses were performed for the key secondary endpoint, which is a composite of CV death, non-fatal MI, or non-fatal stroke, and for the primary endpoint and the key secondary endpoint in the primary and secondary prevention strata to explore further the consistency of clinical benefit of icosapent ethyl. In subgroup analyses of the two cardiovascular risk strata (i.e., primary and secondary prevention), site-level discrepancies in cardiovascular risk group assignment occurring at entry and detected during the study (1.8%) were adjusted to conform with documented medical history data prior to randomization. All efficacy analyses were performed according to the intention-to-treat principle. All tests were based on a 2-sided nominal significance level of 5% with no adjustments for multiple comparisons.

Results Baseline Characteristics

A total of 8,179 patients were randomized and followed for a median of 4.9 years. The patients were well matched in the icosapent ethyl and placebo groups as shown in Table 16 (See Example 1). The secondary and primary prevention according to the adjusted stratification for this study are shown in Table 26.

Total Events for Primary Efficacy Endpoint: The total events for the primary efficacy endpoint showed that of 8,179 patients, there were 1,606 (i.e., 55.2% of the endpoints) first primary endpoints and 1,303 (i.e., 44.8% of the endpoints) additional primary endpoints, for a total of 2,909 endpoint events among the 1,606 patients. There were 762 second events, 272 third events, and 269 fourth or more events. FIG. 13 shows a distribution of first and recurrent events in the patients randomized to icosapent ethyl or placebo before and after the trial. In the overall trial, total primary endpoints were reduced from 1,724 to 1,185 (HR 0.68, 95% CI 0.63-0.74, P<0.0001) with icosapent ethyl as shown in FIG. 13. Within the primary endpoint reductions, first events were reduced from 901 to 705 (i.e., a total reduction of 196), second events were reduced from 463 to 299 (i.e., a total reduction of 164), and additional endpoints were reduced from 360 to 131 (i.e., a total reduction of 179) with icosapent ethyl (See FIG. 13). Using the Wei-Lin-Weissfeld model, the first occurrence of a primary composite endpoint was reduced with icosapent ethyl versus placebo (HR 0.75, 95% CI 0.68-0.83, P<0.0001) as was the second occurrence (HR 0.72, 95% CI 0.62-0.83, P<0.0001). FIGS. 14-16 depict the overall cumulative event curves from the primary endpoint of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, and unstable angina. The overall cumulative events are shown in FIG. 14, the secondary prevention stratum events are shown in FIG. 15, and the primary prevention stratum events are shown in FIG. 16.

The total events for each occurrence of the primary endpoint, inclusive of the first and all subsequent occurrences of primary endpoints components (i.e., cardiovascular death, nonfatal myocardial in fraction, nonfatal stroke, coronary revascularization, and unstable angina) are shown in FIG. 17. Importantly, FIG. 17 shows that the times to first occurrence, second occurrence, third occurrence or fourth occurrence of the primary composite endpoint were consistently reduced in the icosapent ethyl group as compared to the placebo control group. The proportions of first and subsequent primary endpoint events, overall and by component, are depicted in FIG. 18. The risk differences for every 100 patients treated for five years with icosapent ethyl vs placebo control for the components of the composite primary endpoint are shown in FIG. 19.

The total events for each component of the primary and key secondary efficacy endpoints inclusive of the first and all subsequent occurrences of the primary and key secondary endpoints components (i.e., cardiovascular death, nonfatal myocardial in fraction, nonfatal stroke, coronary revascularization, and unstable angina) and key secondary endpoint components (i.e., nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death) are shown in FIG. 20. Importantly, FIG. 20 shows that total events for each component of the primary endpoint were also significantly reduced. In the secondary prevention stratum, total primary endpoint events were reduced from 1,468 to 988 (HR 0.66, 95% CI 0.61-0.72, P<0.0001), and in the primary prevention stratum, from 256 to 197 (HR 0.79, 95% CI 0.65-0.96, P=0.018; P_(interaction)=0.098). Without adjusting for stratification differences, total primary endpoint events in the secondary prevention stratum were reduced from 1,461 to 964 (HR 0.65, 95% CI 0.60-0.71, P<0.0001) and from 263 to 221 (HR 0.86, 95% CI 0.71-1.03, P=0.105) in the primary prevention stratum; P_(interaction)=0.009.

Total Events for the Key Secondary Efficacy Endpoint: FIGS. 21-23 depict the cumulative event curves from the key secondary endpoint of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. The overall cumulative events are shown in FIG. 21, the secondary prevention stratum events are shown in FIG. 22, and the primary prevention stratum events are shown in FIG. 23. Total key secondary endpoints were significantly reduced from 861 to 590 (HR 0.71, 95% CI 0.63-0.79, P<0.0001) with icosapent ethyl versus placebo as shown in FIG. 21. Similar patterns were seen for the key secondary endpoint, both in the secondary prevention (HR 0.70, 95% CI 0.63-0.79, P<0.0001) and primary prevention (HR 0.71, 95% CI 0.55-0.93, P=0.011) strata as shown in FIGS. 22 and 23, respectively, P_(interaction)=0.90. Without adjustment for stratification differences, total key secondary endpoint events in the secondary prevention stratum were reduced from 671 to 478 (HR 0.69, 95% CI 0.61-0.78, P<0.0001) and from 142 to 112 (HR 0.78, 95% CI 0.60-1.00, P=0.047) in primary prevention; P_(interaction)=0.39.

Similarly, the total events for the primary and key secondary efficacy endpoints are further depicted in FIGS. 24-29 as a function of the total cumulative incidence vs years since randomization. This contrasts FIGS. 14-16 and FIGS. 21-23 which report the total events for the primary and key secondary efficacy endpoints as a function of the mean cumulative function vs follow up time in days from randomization. FIGS. 24 and 25 show the overall mean cumulative recurrent events of the primary composite endpoint and key secondary endpoint, respectively. FIGS. 26 and 27 depict the recurrent events of primary and key secondary endpoints for the secondary prevention stratum, respectively. Lastly, FIGS. 28 and 29 further depict the recurrent events of primary and key secondary endpoints for the primary prevention stratum, respectively.

Overall, the results of this study indicated that the use icosapent ethyl was superior as compared to a placebo in reducing total ischemic events, with a consistent benefit in secondary as well as primary prevention.

Conclusion

This study, an analysis of the total events in the REDUCE-IT trial as outlined above in Example 1, indicated a significant reduction in ischemic events with icosapent ethyl versus placebo. More specifically, the results from this study show that there was a 32% relative risk reduction and in total events for the primary composite efficacy outcome. In addition, first events were reduced by 25%, second events were reduced by 28%, and third or more events were reduced by 50%. For every 100 patients treated with icosapent ethyl for five years, approximately 16 total primary endpoint events could be prevented: 1 cardiovascular death, 4 myocardial infarctions, 1 stroke, 8 coronary revascularizations, and 2 episodes of unstable angina. An examination of total events for the key secondary endpoint corroborated the significant reduction in important ischemic events seen with the primary endpoint. There was a consistent benefit in both the secondary prevention and primary prevention strata.

There were significant reductions in the number of total events for each individual component of the composite primary endpoint. This benefit of icosapent ethyl across a variety of different endpoints (i.e., coronary, cerebral, fatal, non-fatal, ischemic events, revascularizations) suggests that the drug benefit is not likely to be explained by triglyceride lowering alone but rather, strongly suggests that there are multiple mechanisms of action of the drug beyond triglyceride lowering that work together to achieve the observed benefits. Basic investigations support this contention. Icosapent ethyl was well tolerated with no significant difference in rates of serious adverse events versus placebo. Although overall rates were low in both treatment groups, and none of the events were fatal, there was a trend towards increased serious bleeding with no significant increases in adjudicated hemorrhagic stroke, serious central nervous system bleeding, or gastrointestinal bleeding. There was a small, but statistically significant increase in hospitalization for atrial fibrillation or flutter noted in the REDUCE-IT study as described in Example 1. Nevertheless, the large number of important ischemic events averted, including a significant reduction in cardiovascular death, provides a very favorable risk-benefit profile. Given the broad inclusion criteria and relatively few exclusion criteria, these results are likely generalizable to a large proportion of statin-treated patients with atherosclerosis or diabetes.

In conclusion, icosapent ethyl 4 g per day (i.e., 2 g per day) significantly reduces total ischemic events in patients with established atherosclerosis or with diabetes and additional cardiovascular risk factors already being treated with statin therapy, with consistent benefits across a variety of individual ischemic endpoints. In patients with elevated triglycerides with cardiovascular disease or diabetes, icosapent ethyl reduces total ischemic events in both secondary and primary prevention. In such patients with fasting triglycerides 135 mg/dL and above, icosapent ethyl should be considered in order to reduce the total burden of atherosclerotic events.

Example 3: The Impact of Icosapent Ethyl on Total Ischemic Events in Statin-Treated Patients

As described above in Example 1, in time-to-first-event analyses, icosapent ethyl significantly reduced the risk of ischemic events, including cardiovascular death, among patients with elevated triglycerides receiving statins. However, these patients remain at risk for first and subsequent ischemic events. Results from Example 2 indicated that the use icosapent ethyl was superior as compared to a placebo in reducing total ischemic events, with a consistent benefit in secondary as well as primary prevention. The objective of the study described in this example was to use pre-specified analyses to determine the extent to which icosapent ethyl reduced total ischemic events in patients from the REDUCE-IT trial.

Methods

The following study was a multi-center, placebo-controlled clinical trial the details of which are described above in Example 1, the REDUCE-IT design. Briefly, the REDUCE-IT trial randomized 8,179 statin-treated patients with triglycerides 135 and <500 mg/dL (median baseline of 216 mg/dL) and LDL-cholesterol >40 and 100 mg/dL (median baseline of 75 mg/dL), and a history of atherosclerosis (i.e., 71% patients) or diabetes (i.e., 29% patients) to icosapent ethyl 4 g per day or placebo. The main outcomes were total primary composite endpoint events defined as cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina and total key secondary composite endpoint events defined as cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. In the context of this study, total events refer to any first event as well as any subsequent event. Differences in total events were determined using other statistical models, including Andersen-Gill, Wei-Lin-Weisfeld (Li and Lagakos), both pre-specified, and a post hoc and joint-frailty analysis.

For the present prespecified analysis, the primary outcome was the total of first plus subsequent ischemic events consisting of the composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina. The composite of hard major adverse cardiovascular events (i.e., cardiovascular death, non-fatal myocardial infarction, non-fatal stroke) are designated as the “key secondary endpoint” per suggestions from the Food and Drug Administration. Exploratory analyses of the total of first and subsequent events were also performed for the key secondary composite endpoint.

Baseline characteristics were compared between treatment groups using the chi-squared test for categorical variables and the Wilcoxon rank sum test for continuous variables. There are several methods for analyzing first and subsequent (recurrent) event data. As a pre-specified statistical method, a negative binomial regression was used to calculate rates and rate ratios for total cardiovascular events, which accounts for the variability in each patient's risk of events. As pre-specified supportive analyses, the modified Wei-Lin-Weissfeld method (Li and Lagakos modification) was used to calculate hazard ratios (HRs) for the time to the first event, second event, or third event. An additional pre-specified analysis, the Andersen-Gill model using a Cox proportional-hazard with the counting-process formulation was performed to model the total events. In addition, in order to account for informative censoring due to cardiovascular death, the HR for total non-fatal events was calculated using a joint frailty model (See Rondeau V. Joint frailty models for recurring events and death using maximum penalized likelihood estimation: application on cancer events. Biostatistics. 2007; 8:708-21). The joint frailty model simultaneously estimates hazard functions for non-fatal and fatal CV events and takes into account the fact that patients who are prone to have nonfatal events have an elevated risk of a cardiovascular death. The application of the joint frailty model used a gamma distribution for the frailty term.

To improve the performance and validity of the statistical models, a bundling approach was employed, whereby non-fatal events occurring on the same day as a CV death were excluded, and at most, one non-fatal event was counted on any given day (e.g., for coronary revascularization occurring after a myocardial infarction which eventually resulted in the patient's death, only the death would be included). Statistical analyses using the full adjudicated endpoint events dataset without exclusions using this bundling approach were also determined.

All efficacy analyses were conducted in accordance with the intention-to-treat principle. All tests were based on a 2-sided nominal significance level of 5% with no adjustments for multiple comparisons, consistent with prespecified plans for such endpoints.

Results

A total of 8,179 patients were randomized and followed for a median of 4.9 years. The baseline characteristics were well matched across the icosapent ethyl and placebo groups as shown in Table 28. At baseline, the median triglyceride levels were 216 mg/dL with median LDL-C levels of 75 mg/dL. Additional baseline characteristics across treatment groups and for patients with no events, a single event, and multiple subsequent events are shown in Tables 28 and 29, respectively.

Percentages are based on the number of subjects randomized to each treatment group in the ITT population (N). In general, the baseline value is defined as the last non-missing measurement obtained prior to the randomization. The baseline LDL-C value obtained via Preparative Ultracentrifugation was used, unless this value was missing. If the LDL-C Preparative Ultracentrifugation value was missing, then another LDL-C value was be used, with prioritization of values obtained from LDL-C Direct measurements, followed by LDL-C derived by the Friedewald calculation (only for subjects with TG <400 mg/dL), and finally LDL-C derived using the calculation published by Johns Hopkins University investigators.¹For all other lipid and lipoprotein marker parameters, wherever possible, baseline was derived as the arithmetic mean of the Visit 2 (Day 0) value and the preceding Visit 1 (or Visit 1.1) value. If only one of these values was available, the single available value was used as baseline. ^([1])P Values from Wilcoxon rank-sum test for continuous variables and chi-square test for categorical variables. ^([2])Race as reported by the investigators. ^([3])Body-mass index is the weight in kilograms divided by the square of the height in meters. ^([4])Westernized region includes Australia, Canada, Netherlands, New Zealand, United States, and South Africa. ^([5])Eastern European region includes Poland, Romania, Russian Federation, and Ukraine. ^([6])Asia Pacific region includes India. ^([7])The summary is based on the data collected from CV history Case Report Form (CRF). ^([8])Two outliers of Carotid Stenosis (%) with a value over 100% are excluded from the analysis. Carotid Stenosis (%) data reported in categorical format of >x % and <y % is analysed as x % and y %, respectively; and data reported as x % to y % is analysed as an average of x % and y %. ^([9])Dual anti-platelets were classified as such if both components have a robust history of regulatory approval affirming anti-platelet effects, thus excluding combinations where one element lacks robust regulatory approval (e.g, Aspirin + Magnesium Oxide is classified as a single agent because the latter component lacks robust regulatory support as an anti-platelet agent).

At baseline the percentage of patients taking at least one other cardiovascular medication including antiplatelet agents was (79.7 and 79.1%), beta blockers (71.0% and 70.4%), angiotensin converting enzyme (ACE) inhibitors (51.7% and 52.1%), or angiotensin receptor blockers (27.1% and 26.8%) in the icosapent ethyl and placebo treatment arms, respectively.

Total Events for the Primary Efficacy Endpoint: Across 8,179 randomized patients, there were 1,606 (i.e., 55.2%) first primary endpoint events and 1,303 (i.e., 44.8%) additional primary endpoint events, for a total of 2,909 endpoint events as shown in Table 30 and FIGS. 30, 31A and 31B.

The proportions of first and subsequent primary endpoint events, overall and by component type, are depicted in FIG. 32. There were 762 second events, 272 third events, and 269 fourth or more events. Overall, total (i.e., first and subsequent) primary endpoint event rates were reduced to 61 from 89 to per 1000 patient years (i.e., rate ratio (RR) 0.70, 95% CI 0.62-0.78, P<0.0001) with icosapent ethyl as shown in the central illustration in FIG. 33. Using the Wei-Lin-Weissfeld model, the first occurrence of a primary composite endpoint was reduced with icosapent ethyl versus placebo (i.e., HR 0.75, 95% CI 0.68-0.83, P<0.0001) as was the second occurrence (i.e., HR 0.68, 95% CI 0.60-0.78, P <0.0001). There was a 30% relative risk reduction in the total (first and subsequent) ischemic events for the primary composite endpoint with icosapent ethyl. First events were reduced by 25%, second events by 32%, third events by 31%, and fourth or more events by 48%.

The cumulative events over time are shown in FIGS. 34A and 34B. Specifically, FIG. 34A depicts the total (i.e., first and subsequent) and time to first primary composition endpoint events and FIG. 34B shows the key secondary endpoint events. Total key secondary endpoint event rates were significantly reduced to 32 from 44 per 1000 patient years for icosapent ethyl versus placebo, respectively (i.e., RR 0.72, 95% CI 0.63-0.82, P<0.0001) with icosapent ethyl versus placebo as shown in FIG. 34B. The times to first occurrence, second occurrence, third occurrence or fourth occurrence of the primary composite endpoint were consistently reduced as shown FIG. 35 with icosapent ethyl. There were similar results for the models irrespective of whether bundling and/or single accounting was employed as shown in Tables-31-33.

Total events for each component of the primary endpoint were also significantly reduced as shown in FIG. 36, FIG. 30, and Table 34.

FIGS. 37A and 37B show the total primary and key secondary composite endpoints in selected subgroup analyses by the negative binomial model. The risk differences for every 1000 patients treated for five years with icosapent ethyl for the five components of the composite primary endpoint are shown in FIG. 38; approximately 159 total primary endpoint events could be prevented within that time frame: 12 cardiovascular deaths, 42 myocardial infarctions, 14 strokes, 76 coronary revascularizations, and 16 episodes of hospitalization for unstable angina. FIGS. 39 and 40 show the forest plot for total primary and key secondary composite endpoint events and first second, and third occurrences for the reduced dataset with unadjusted and adjusted values, respectively. FIGS. 41 and 42 show the forest plots for the total primary composite endpoint events and total key secondary composite endpoint events and first, second, and third occurrences for the reduced data with unadjusted values, respectively. FIGS. 43 and 44 show the total primary composite endpoint events and key secondary composite endpoint events and first, second, and third occurrences for the reduced data set with adjusted values, respectively. FIGS. 45 and 46 show the total primary and key secondary composite endpoint events and first, second, and third occurrences for the full data set for the unadjusted and adjusted values, respectively.

The study drug adherence in patients with recurrent events was also explored. At the time of a first primary endpoint event (fatal or nonfatal), 81.3% (573/705) of icosapent ethyl and 81.8% (737/901) of placebo patients with a first primary endpoint event were receiving randomized study drug. At the time of subsequent primary endpoint events (fatal or nonfatal), 79.7% (188/236) and 79.5% (299/376) of patients with a second event, 68.1% (49/72) and 74.1% (106/143) of patients with a third event, and 68.0% (17/25) and 71.6% (48/67) of patients with a fourth event were receiving randomized study drug in the icosapent ethyl and placebo groups, respectively. Therefore, the majority of the first, second, third, and fourth events occurred while patients were on randomized study treatment. Numerical differences in study drug adherence among patients with recurrent events were not statistically significant between treatment groups.

Conclusion

In these total event analyses of the REDUCE-IT clinical trial as described in Example 1, large and significant reductions in total ischemic events with icosapent ethyl versus placebo were found in the total event analyses. Three prespecified and one post hoc analyses with various statistical methodologies demonstrated consistent effects on total ischemic events, with substantial relative and absolute risk reductions. There was a 30% relative risk reduction in the total (i.e., first and subsequent) ischemic events for the primary composite endpoint with icosapent ethyl. For every 1000 patients treated with icosapent ethyl for five years, approximately 159 total primary endpoint events could be prevented. Total events for the hard MACE key secondary endpoint also demonstrated large and clinically meaningful reductions, which further corroborated the significant reduction in important ischemic events seen with the primary endpoint.

There were significant reductions in the first, subsequent and total ischemic events for each individual component of the composite primary endpoint. This benefit of icosapent ethyl across a variety of different ischemic endpoints (e.g., coronary, cerebral, fatal and non-fatal events, and revascularizations) suggests that the drug benefit is not likely to be explained by triglyceride lowering alone and suggests strongly that there are multiple mechanisms of action of the drug beyond triglyceride lowering that may work together to achieve the observed benefits.

Icosapent ethyl was well tolerated with no significant differences in rates of serious adverse events versus placebo. Although overall rates were low in both treatment groups, and none of the events were fatal, with icosapent ethyl there was a trend towards increased serious bleeding albeit with no significant increases in adjudicated hemorrhagic stroke, serious central nervous system bleeding, or gastrointestinal bleeding. There was a small, but statistically significant increase in hospitalization for atrial fibrillation or flutter endpoints observed in patients from the clinical trial. Nevertheless, the large number of important ischemic events averted with the drug, including a significant reduction in fatal and nonfatal stroke (28%), cardiac arrest (48%), sudden death (31%) and cardiovascular death (20%), in indicative of a very favorable risk-benefit profile.

The patients for the REDUCE-IT clinical trial represent a population at high risk for ischemic events, as suggested by the annualized placebo event rate (5.74%), which was expected per study design and is consistent with historical data for similar high-risk statin-treated patient populations. It is therefore not surprising that the total atherosclerotic event burden was also high for REDUCE-IT patients. Substantial and consistent risk reduction with icosapent ethyl was observed in total event analyses for the primary endpoint, each contributing component, and the key secondary endpoint. Time-to-first-event results provide low number needed to treat (NNT) values (i.e., 21 for the primary endpoint; 28 for the key secondary endpoint); the total event analyses results provide incremental evidence of substantial reduction of the total atherosclerotic burden with icosapent ethyl in these patients, with 16 total primary events prevented for every 100 patients treated with icosapent ethyl for 5 years. Without intending to be bound by any particular theory, given the broad inclusion criteria and relatively few exclusion criteria, these results may be generalizable to a large proportion of at-risk statin-treated patients with atherosclerosis or diabetes.

Study drug adherence in patients with recurrent events was strong in both treatment groups at the time of their first primary endpoint event, decreasing somewhat across both treatment groups from the occurrence of the first to the fourth event. For example, at the time of a first occurrence of a fatal or nonfatal primary endpoint event, 81.3% of icosapent ethyl and 81.8% of placebo patients with a first primary endpoint event were on study drug; these rates decreased to 68.0% and 71.6% for patients with a fourth primary endpoint event.

The primary study results for the REDUCE-IT trial and the recurrent and total endpoint event findings discussed herein stand in stark contrast to cardiovascular outcome studies with other agents that lower triglyceride levels and with low-dose omega-3 fatty acid mixtures, where cardiovascular outcome benefit has not been consistently observed in statin-treated patients. EPA has unique lipid and lipoprotein, anti-inflammatory, anti-platelet, anti-thrombotic, and cellular modifying effects, all of which may contribute to benefits in atherosclerotic processes such as reduced development, slowed progression, and increased stabilization of atherosclerotic plaque. The aggregate contribution of these EPA-related effects may contribute to the large observed reductions in total ischemic events with icosapent ethyl.

Each total event analysis model employed in this study provides statistical handling of subsequent events, with some distinct and some overlapping strengths. Despite differences in statistical methodologies, the consistency of findings across the models speaks to the robustness of the study conclusions and the underlying outcomes data.

In conclusion, icosapent ethyl four grams daily (i.e., administered two grams twice daily) significantly reduces total ischemic events in statin-treated patients with well-controlled LDL-C and cardiovascular risk factors including elevated triglycerides with consistent benefits observed across a variety of individual ischemic endpoints. In such patients, icosapent ethyl presents an important treatment option to further reduce the total burden of atherosclerotic events beyond that provided by statin therapy alone.

Example 4: The Impact of Icosapent Ethyl on Ischemic Events in Statin-Treated Patients as a Function of Baseline Triglyceride Tertile

The objective of the following example was to determine the extent to which icosapent ethyl reduced ischemic events in patients from the REDUCE-IT trial, as described in Example 1 as a function of triglyceride level.

In the REDUCE-IT trial as described in Example 1, patients underwent a screening visit to determine eligibility, including testing of statin-stabilized triglyceride levels. If patients met inclusion and exclusion criteria, including triglyceride levels, they could then be entered into the study at a subsequent randomization visit. Triglyceride levels were also measured from blood drawn at the randomization visit, but randomization values were not utilized for study qualification. Randomization values did not always fall within the inclusion criteria that were previously met within qualifying visits. In total, the baseline triglyceride levels of the patients ranged from 81 mg/dL to 1401 mg/dL.

The patients were then categorized into three tertiles based on their triglyceride levels. The lowest tertile range included those patients with triglyceride levels of ≥81 to ≤190 mg/dL with a median triglyceride level of 163 mg/dL, the middle tertile range included those patients with triglycerides of >190 to <250 mg/dL with a median triglyceride level of 217 mg/dL, and the uppermost tertile range included patients with triglyceride levels of >250 to 1401 mg/dL with a median triglyceride level 304 mg/dL. The baseline characteristics of the patients to include the triglyceride category by tertile are shown below in Table 34.

FIG. 47 is a forest plot demonstrating that the total events (i.e., first and subsequent) for the primary composite endpoint of CV death, non-fatal stroke, non-fatal myocardial infarction, coronary revascularizations, or unstable angina requiring hospitalization was reduced in all patients across the entire triglyceride range and within each of the defined triglyceride tertiles. Similarly, FIG. 48 demonstrates that the time to first event of the primary composition endpoint was reduced across the entire triglyceride range.

In conclusion, patients from the REDUCE-IT clinical trial with baseline triglyceride levels across all tertiles (e.g., between 81 mg/di to 1410 mg/dl), regardless of their specific triglyceride baseline level, benefited from the administration of 4 g of icosapent ethyl per day and experienced statistically significant reductions in not only the time to first cardiovascular event, but also, total cardiovascular events in both the primary and key secondary composite endpoints.

The results from the REDUCE-IT clinical trial showed a significant cardiovascular benefit associated with the administration of icosapent ethyl. It is contemplated that a number of factors contribute to the significant reduction in the cardiovascular risk. Without intending to be bound by any particular theory, one of the contributing factors might relate to the dose and formulation of the icosapent ethyl administered to the patients, in marked contrast to previous studies of omega-3 fatty acid studies. An additional contributing factor could relate to the patients' blood pressure. For example, prespecified exploratory analyses of icosapent ethyl with no adjustment for multiple comparisons showed average placebo-corrected reductions from baseline in systolic blood pressure of 1.3 mm Hg (95% CI, 0.9 to 1.6) and in diastolic blood pressure of 0.5 mm Hg (95% CI, 0.3 to 0.7) as shown in FIG. 49. FIG. 49 shows repeated-measurements analysis of change from baseline blood pressure over time by a mixed effects model for the ITT population (icosapent ethyl: n=4089, placebo: n=4091, maximum number of observations per patient=6). These differences appear to be modest, but it is contemplated, that they might contribute to the benefits of icosapent ethyl. It is further contemplated that biomarkers (e.g., the ratio of EPA to arachidonic acid) and blood pressure, may also provide an understanding of the effects of icosapent ethyl and potential mechanistic insight for the observed reduction in cardiovascular risk. Further, as common in long-term clinical trials, study drug adherence waned overtime. However, despite the waning there was a long-sustained treatment effect on total events as shown in FIG. 50.
